What is the difference between Super User and Web Application Stack Exchange 'groups'?

Question

How come the following question was migrated from Super User to the Web Applications Stack Exchange site?

How to generate a YouTube playlist of the most recent videos from each channel you follow?

but then when I created this question, it was migrated back to Super User?

How to prevent Chrome from creating a nested folder when bookmarking all opened tabs into a specific folder?

Both questions are related to dealing with applications, one is a browser and the other is a website, but can that not also be considered an application?

Answer 1

Super User handles "question about computer software or hardware", while Web Applications handles "question about web applications".

When it is about browsers handling websites/web apps, a simple litmus test:

• If it is about operating browsers that are independent of the web sites, then it is most likely more suitable on Super User.
• If it is about operating web apps that are independent of the browsers, then it is most likely more suitable on Web Applications.

For this specific case,

• "How to prevent Chrome from creating a nested folder when bookmarking all opened tabs into a specific folder?" is a Chrome-specific question, but independent of web sites of the opened tabs
• "How to generate a YouTube playlist of the most recent videos from each channel you follow?" is a YouTube-specific question, but independent of the browsers.
