I have set up a workflow where I star or favorite a question that I want to "follow". I have found that this makes it easy for me to go back and see if there have been updates. (I don't always get notifications of things going on in the question/answers.) Then when I'm done or the question is answered, I remove it from my favorites.
Is there a better way?
I want to actually use favorites for what it was intended: Good answers that I want to refer back to in the future. These don't always come up quickly on Google Search or the internal Stack Overflow search.
These are similar questions, but not exactly the same. Some are old and seem to be no longer applicable.
