We'll be lowering the vote temp slightly for individual member votes and deals. The temperature for each deal is dynamically calculated based on several variables but obviously the biggest one is the effect of a member vote. Each member has their own voting power based on their historical interaction on HUKD and deals they've found.
As the site gets bigger and more members vote there is "inflation" in the deal temp as it becomes easier for a deal to become hotter. We play with the hot deal tipping point but also with member vote influence to deflate this from time to time. Right now I think there are too many deals getting hot so we are going to tweak that down a bit (i.e. there's already 5 pages of hot deals today and really we know there aren't that many truly hot deals in a day).
Anyways, this is just a heads up to let you all know :)
