The title says it all.
My favorite is probably “Your thoughts on Hume’s Criticism of Induction”.
The thread offers some of the best free commentary on the matter of induction, philosophy of science and the nature of certainty.
There have been a couple of threads on cosmology that have been superb as well, but I can’t think of the title of any at the moment.
I don’t have a list of favorite threads, but of favorite posts/replies. See my profile page, or the list copied below:

In fact that whole thread, from that point on, is a good discussion of Rand’s method and why the fact it is not ‘academic’ is what’s so damn good about it!
No better way to spend your Saturday night than searching through OO.net for great philosophic discussion
Russell’s Paradox is a great thread centering around philosophy of language and Rand’s theory of concept-formation
