I have noticed, on occasion, new questions appearing with no upvotes but marked as a favorite by 1 user. I originally thought that perhaps someone marked it as a favorite to keep an eye on it during its early life.
However, today I found that I can actually mark my own questions as favorite and now suspect that people may be marking their new questions as favorites too.
What is the actual point in marking your own question as a favorite? You already get updated with new votes, answers and comments on your own questions. What additional functionality does favoriting your own questions offer?
