Based on their analysis, here are the big take-aways as to what issues web developers are facing:
Cross-browser compatibility is becoming less of an issue over time
Web technologies are becoming more important in mobile development
Finally, the researchers found that since 2009, an increasing number of HTML5 questions have had to do with device detection and local storage, while more and more CSS questions are about the viewport meta tag, which is used to adjust the layout on mobile browsers. These findings, the researchers argue, are strong evidence of the growing importance of web technologies for mobile development.
There are more interesting nuggets of information in the study, if you really want to dig in further and learn more about the questions web developers are asking. Despite being an academic article, it's surprisingly readable. Have at it!
