From time to time I read very interesting questions and answers and I would like to keep track of them in order to refer to them later. Does this site provide a bookmarking mechanism or something similar that allows a user to store the interesting pages for future access?
The idea of stackexchange is probably to use "favourites" for this, which Johannes_B mentioned in his comment. However I consider them pretty useless (no notification, many false positives...).
Instead I use RSS feeds to keep track of interesting question. At the bottom of every question there is a link "question feed", which can be used to subscribe to this question.
Notifications etc. are then handled by the program you use to retrieve the feed.
The way Stack Exchange handles bookmarks is through something called favourites. It's the star just below the question voting buttons:
Once a question is starred, you'll find it in your favourite's tab (with the URL
//<site>/users/<userid>?tab=favorites). Updates to favourites are indicated by a boxed number next to the tab when viewing your user profile:
You can only add questions to your list of favourites and this will necessarily include the answers associated with it. You can, of course, also bookmark any page using your browser's default bookmarking functionality.
