Is Photography such a low volume site that https://photo.stackexchange.com/questions/56891/why-would-i-bother-to-participate-any-further-on-this-web-site (now migrated to their meta: https://photo.meta.stackexchange.com/questions/4593/why-would-i-bother-to-participate-any-further-on-this-web-site ) somehow qualifies as hot? It is not a clever title to make you read something about photographs, it's exactly what it appears to be:
35 views doesn't feel very hot to me!
The question has a lot of comments, but the accepted answer to How are questions in the 'hot' tab selected? makes no mention of comments at all, just views, score, answers, answer score, and age.
