How are 'Hot Threads' Determined?

[bob012345]

Are 'hot threads' universal across PF or are they tailored to individual user's activity? If I start a thread and it becomes 'hot' is everyone seeing it as 'hot'? How does that work? Just curious. Thanks.

Edit : I think I figured it out. If one is in a specific forum it is different. If one is in the top level, not in any forum, it must be universal?

There are several conditions that must be met. Like X views, X replies, X usergroup the starter is in etc.
