This question already has an answer here:
I am well aware of how the Favorite button on the questions works and where I go to find my or anyone else's favorite questions.
I am also well aware of the fact that adding a question to the favorites improves its "hotness score" (and who does not want to show his answers on the main page), since it is public reputation of the question. Correct me if I am wrong.
Adding 1 and 1 made me look into the profiles of some highly-ranked users (on various sites) and the amount of the favorite questions closely matched the amount of their answers. The OP can do probably the same for his questions, but highly-ranked askers are not so common.
Yes. I know that hot questions are not substitute for a good questions and good answers, but the visibility helps.
Everyone have limited amount of votes per day, which affects questions all around, but are the Favorites limited in any way? Is this considered as ethical or is it advisable?
