I have seen the posts about how the questions are selected for the "hot" tab on SO, but I think it's weird that the list often contains questions with < 20 views, no answers, no edits, and < 2 comments. Does anyone else think there should be minimums of > 20 views OR > 2 answers OR > 3 comments to be included in this list?
I don't think that's necessary. There's a time component in calculating hotness. The formula also uses the log of the views, not the raw number of views, so if a question gets to the "hot" tab on views alone, it will drop off quickly if it doesn't get any answers, edits, or votes.
