When someone asks a question I often don't know the exact answer but have a suggestion for the first thing to try, or sometimes they don't give enough info and I need more details. When I do this, I always keep going back and checking if anything new comes up.
I'm notified in the header if there's a comment on my answer, but not a comment on other people's answers. So this feature is almost useless for me.
What is the best way to keep track of any change at all to questions you're helping find an answer to? Do you bookmark them and keep re-visiting? Should I favourite the question (seems this would be miss-using the reputation system). Or just don't bother going back unless someone comments on your answer?
