Thanks @RobLa-WMF and @Qgil-WMF for the summary in-topic and the first iteration to find good main topics! :)
I'm almost fine with the topics, they look as they would cover a lot of subtopics and keep enough space for discussions into different directions (which is, as I understand it, one goal, to find new/other solutions and think about ways how to fix/implement them, or to get a high-level plan). However, one suggestion for this point:
> Updating the MediaWiki user experience. The MediaWiki UX for readers hasn't changed much in a decade and it is showing an age
Even if we've VisualEditor, a lot of editors still want and like to use the source/wikitext editor (and I understand why, it's a good and powerful editor, if you know the wikitext syntax. Having this in mind, the MediaWiki UX hasn't changed a lot for both, readers and editors. So probably we should open the discussion for both parties. For the editing side I've task T104479 in mind, which tries to solve this, so the question could be: How can we attract editors to use it, or better test it in an early state and give feedback, so it will be a success from the beginning (not like the first start of the VE itself)? This is just an idea, but, to come to the point, I wouldn't limit the topic to readers only (even if they're really important, too).
