I've mentioned something like this before, but I think a monthly 'Sequence Topics' thread would be a good place for new users to talk about all the background topics. It would be especially convenient to have such threads automatically and visibly linked from the Sequence pages.
(LucasSloan and inklesspen also made recent suggestions along these lines.)
I'm strongly pro-necropost, so I'm not sure I agree. Can't people just watch their inboxes for new posts in their threads, and add notes to the wiki and the Sequence posts saying "Asking questions is strongly encouraged, regardless of the thread's age"? New threads would put an extra step between encountering the question and asking it.
On the other hand, that could contribute to the "I should RTFT...wait, 2000 comments? Forget it" failure mode, so I don't know. (Although the fact that we have threading at least helps.)

Requested features... sure, go ahead, but bear in mind we may not be able to implement for a while.
