Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
There must be a way to 'follow' a question or even a user through SE (i.e., it's easy to do it with browser bookmarks).
Click the Star under the vote count for any question to mark it as a Favorite.
