The COVID-19 pandemic has affected the way people use social media in a particular manner. The paper aims to investigate the impact of the pandemic on the use of social media, taking into account the sex and personality types of users in Poland. The survey involved 469 active users of social media. The data were analysed with statistical methods. A significant part of the respondents believed that the COVID-19 pandemic affected the way they used social media. They pointed out that the most common social media use drivers were immediate needs, often of pragmatic nature, such as rapid communication and exchange of information, and social needs. Among the survey population, it was the women who were more active on social media, particularly regarding Instagram. They were also more active on Pinterest and Snapchat. Men were more active on YouTube. Extraverts published more often on Facebook, Instagram, Snapchat, or Pinterest by a wide margin. They were also more active in general and more often judged social media content. The respondents indicated social platforms they believed would gain or lose popularity in the nearest future. The overall conclusion is that the pandemic may be a good time to launch new social platforms or promote less popular ones with new functionalities and narrow targets.

The quality of healthcare service websites gains particular importance in the time of the pandemic,asthe popularity of electronic services grows. This applies to infectious disease hospitals as well, often on the front line of the effort against COVID-19. The paper aims to assess the quality of infectious disease hospital websites in Poland in light of the COVID-19 pandemic. The research covered 91 websites. The first stage was an analysis of selected technical attributes of the websites (including website performance, SEO quality, website availability, and mobile-friendliness) with selected online tools, such as Google PageSpeed Insights, Blink Audit Tool, Backlink Checker, andwebsite accessibility evaluation tool(WAVE). The data were then analyzed with statistical methods. The next step was to analyze the content of the websites. The research has shown that most of the websites were of satisfactory quality, apart from those that were not mobile-ready. The following keywords were found most often on the hospital websites: SARS-CoV-2, COVID-19, smear, specialist care clinic, isolation, telephone consultations, sample collection center, support, coronavirus, recommendations, patient registration, signs of disease. The research suggests that the quality of infectious disease hospital websites in Poland is significantly diversified in search engine optimization, mobile-friendliness, and needs of people at risk of digital exclusion.

Purpose Activities on social platforms affect the audience. They may impact brand perception, purchasing decisions or motivation to act. Motivation makes people behave in certain ways. The purpose of this paper is to analyse the use of social media and its impact on intrinsic motivation, with a focus on Generation Z users (born between 1994 and 2002). Design/methodology/approach The authors conducted multifaceted survey research among full-time and part-time students of one of the largest universities in Poland. The survey was carried out on students of three major fields of study. The analysis involved 427 questionnaires. The data was analysed both with unidimensional and two-dimensional statistical analysis. Findings Although the respondents indicated some “motivational aspects” of social media usage, most of them were characterised by a passive attitude and infrequent activity on such websites. Not many of the respondents published actively. The respondents expected valuable content but were not inclined to disseminate it. Originality/value Publishing of own content and ability to view others’ content in social media may not be enough to increase the user base of a social platform. One way to do this may be narrowing down or diversification of the array of additional services and functionalities that induce users to increase the use rate.

Website users have increasingly high expectations regarding website quality, starting from performance and ending up with the content. This article provides a list and characteristics of selected website quality indices and testing applications that are available free of charge. Aggregated website quality indices were characterised based on a review of various source materials, including the academic literature and Internet materials. Aggregated website quality indices are usually developed with a less specialised user (customer) searching for descriptive information in mind. Their presentation is focused on aesthetic sensations. Most frequently, their values are expressed in points or percent. Many of these indices appear to be of little substantive value, as they present approximate, estimated values. These indices, however, are of great marketing value instead. Specific (“single”) indices are of a specialised nature. They are more difficult to interpret and address the subtle aspects of website and web application functioning. They offer great value to designers and software developers. They indicate critical spots which affect the website quality. Most of them are expressed precisely, often up to two or three decimal places, in specific units. Algorithmic tests for website quality, whose results are presented using indices, enable a reduction in the cost intensiveness of tests as well as an increase in their number and frequency, as the tests are repetitive and their number is not limited. What is more, they allow the results to be compared.

The success of a rural tourism business largely depends on promotional activities. Having developed a tourist product, owners of rural tourism facilities should therefore inform the buyers about it. Usually, they rely on websites and social media for this purpose. However, for a website to fulfill its function, it should be of high quality. The improvement of website quality can be achieved through measures which include search engine optimization (SEO) and content and graphics optimization. The purpose of this paper is to assess the potential of image optimization on websites of Polish rural tourism facilities. The research covered 1000 paid domain websites. The largest part of the sites surveyed were rated good in terms of graphic file optimization. In spite of this, it was possible to reduce the size of graphic files covered by this study and used in the research model by as much as 67% without significantly deteriorating their quality. This research showed that image optimization has no direct impact on the outcome of an SEO audit, and that images can be optimized even for websites with high final scores.

The paper investigates the accessibility of local government websites. It focuses in particular on disability, e-administration, and web accessibility standards for the visually impaired. The research involved 182 websites of local government bodies of the Małopolskie Voivodeship (Poland). It employed selected automated testing applications. The occurrence of selected accessibility tools on the websites was verified with a cognitive walkthrough. A questionnaire survey was conducted as well. Results of the automatic measurements were standardized using the unitarization method. The effort yielded an aggregate final score for each website in the form of the AAR (Aggregate Accessibility Rating). It was used to build a ranking list of the websites and order them by the accessibility criterion. The websites achieved 57.23% of the available AAR points in total. This indicates there is a great opportunity for improvement in the accessibility of the investigated websites (in the employed research design). Moreover, municipalities were found to be heavily committed to the questionnaire survey, which is indicative of the importance and relevance of the problem of accessibility and quality of public websites.

This paper aims to review, characterize and comparatively analyze selected organizations’ analytics maturity models. Eleven various organizations’ analytics maturity models (AMMs) were characterized. The models’ characteristics were developed based on an academic literature review as well as reports and publications shared by analytics sector operators. Most of the analyzed models comprised five analytics maturity levels. Comprehensive descriptions of an organization’s analytics maturity levels were available for all models. However, no detailed description of the assessment process or criteria for placing an organization at a specific analytics development level were available in all cases. Selected analytics maturity models were described in such a detailed manner that their application in an independent assessment of an organization’s analytics maturity was possible. In the future, an increase is expected in both the number and availability of new analytics maturity models, in particular those personalized and dedicated to a specific sector or business, and the number of entities involved in an assessment of an organization’s analytics maturity and the implementation of data analytics in organizations. The article presents and summarizes selected features of eleven various organizations’ analytics maturity models. This is the firstever such extensive review of those models.

There are many techniques available today for publishing maps in web browsers. The material is often created using geographical information systems (GIS). The performance, most often understood as the speed of loading the application into a web browser, is the determinant of the viewing experience. The performance of a map application can be improved through such process as minification. The purpose of the study is to measure the impact of minification on the performance of the map component.Code minification was performed by selected web applications. The performance of two applica-tions, GTmetrix and Dareboost, was tested. Two research questions have been posed: RQ1: How great a reduction in the size of component files of an application can be achieved with minification?and RQ2: How will the minification affect the performance of a web browser map application? The research has shown that the model applications were performing relatively poor, in particular, on mobile devices. The minification reduced the size of HTML, CSS, and JavaScript files by about 11%, which had a slight impact on application performance (in the employed research de-sign). It has been demonstrated that minification was insufficient for improving significantly the performance of the tested applications. Additional compression of image files is recommended.

Interactive data visualisations are popular and come in different forms, from static raster files to dynamic and complex proposals. The usability of the applications can be increased through the improvement of their technical attributes such as a reduced number of external components or image file compression. The objective of the paper is to analyse the correlation between raster compression and the performance of a map application. The research involved an application created specifically for this purpose. Raster compression and performance were measured using selected online tools. Raster compression has been demonstrated to enhance map application performance, although not all performance indicators improved.

Purpose Almost two decades after diagnosing the link rot phenomenon, and in spite of the universal character of the bit rot phenomenon, the need for reminding about these is still valid. This is because it appears that digital device users have become accustomed to them. The bit rot and link rot phenomena describe the inability to access specific contents or the inability to use specific digital resources. This paper aims to answer the question as to whether it is possible to eliminate the link rot and bit rot phenomena from the internet space. Design/methodology/approach The link rot and bit rot phenomena were characterised based on a review of various source materials, including the academic literature and internet materials. Findings The phenomena known as bit rot and link rot have already been well researched and described. Research has revealed the reasons for their occurrence, and also offered recommendations on how to minimise their occurrence. In the current digital ecosystem, however, it is not possible to completely eliminate the link rot and bit rot phenomena. Research limitations/implications One can forecast that the link rot phenomenon will intensify and the internet resources will be even more unstable, because more and more new, highest-level domains which are purchased are emerging. Originality/value The study compares the phenomena of bit rot and link rot, even though they are usually considered separately. Moreover, it presents the terms of “digital bumps”, which cause “digital tsunami”.
