I would like to hear your input on this, should we block the capacity to favorite a question unless the question has been upvoted? I see lots of questions which have more favourites than votes do you think this is bad?
People favorite questions for all kinds of reasons that aren't synonymous with upvoting. Sometimes the question is bad and the user wishes to keep an eye on it. Sometimes it's because the question might be good enough to answer if an edit is made, such as an "on hold" question. Sometimes one finds one of the answers exceptional, but doesn't think the question is all that good. This would be like insisting a user upvote a question before bookmarking it. I do not support your request.
I am one of the people who does this occasionally. One of my motives for roaming on our site is to search for material: nice questions that I can imagine turning into a homework problem, or into a contest question (junior high or high school level).
When I find such a question I will favorite it. As a kinda bookmark so that I can find it again later. If the OP has put the usual amount effort into it, sure, I will upvote. But upvoting a PSQ just doesn't feel right. In those cases my appreciation belongs to whoever composed the problem.
FWIW as of today my list of favorites runs into 18 pages. May be a quarter of them are of this material search -type. I dare not guess how many of those are without my upvote. At least one of them was deleted (by the OP).
Anyway, I oppose this suggestion. The star belongs to the question, the upvote to the asker.
