More fun than Facebook, more relevant than Reddit and more direct than Digg, Recent changes is the ticker at the heart of RationalWiki's lively and lovely community. It's the natural home of the block log, and is the cause of many improvements to articles when someone edits a random page and everyone is reminded of its existence. It's also a measure of RW's active and inactive periods, with editing dropping to one every twenty or thirty minutes some weekday mornings (UTC), and stuff almost hurtling by in the evening. Liquid threads conversations do tend to clog it slightly though, even with the javascript tidy-upper thing.
