The biggest problem with an FAQ thread is that it eventually ends up being a collection of random questions THAT CANNOT BE INDEXED IN ANY WAY.

Imagine having to dig through 10 pages of questions just to find the answer you were looking for, wouldn’t that be even more annoying?

And quite honestly the Wiki is very comprehensive, and with the recent creation of the Knowledge Base, you’d have to try REALLY hard to not be able to find an answer to your question (unless it’s something super obscure, in which case the user is probably better off starting his/her own thread about it anyway).

So in essence, FAQ threads are obsolete, especially since the Knowledge Base was created pretty much for the exact same purpose.
