it is automatically "kicked" back to the top of the Latest page because it is a hot topic. This happens at 25 replies, 50, replies, 75 replies, etc. We call this a "milestone."

Threads which are on the Latest page because they are milestones have the little blue triangle (and say "Milestone" with the number of replies, below the thread title).

Folks who don't want to see these can turn them off with the filter bar at the top of the Latest page -- set it to "No milestones"
