Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
As a meta post for Stack Apps only, in other Stack Exchange site, we have different description in the "How To Ask" side bar. In StackApps only the required tags are displayed in the side bar and my expectation is, the change is only for the StackApps site.
