I agree 100% with the OP. It's not all about specific guides, it's those little things that you don't THINK is important by itself, but at some point in the last 5 years someone else has asked that question... and had it answered.
Without that resource, there are going to be a LOT of the same questions popping up on the new forums. As forum-dwellers are the minority, this will also means a lot of frustrated people that are googling for answers won't find them.
