I'm confused... About Discussion

Hi, dust, i am clueless why Mylot had this tab too, what really constitute "hot" under this, i think probably only the Admin. can give you the right answer to your question. There are some discussion reached more than hundred responses which do not make into that tab, which tell me the number of responses is not the factor in getting inside hot response tab. It is also unclear whether those discussion make their way inside the tab really make a bit more per response or not. I am quite interested to know how is that work out too...
