The same reason we have http://68kmla.org/forums/archive online. We covered thousands of Mac problems and how to repair them on the old forums. They were a great resource to everyone. If we archive them, we can then pull out a few choice ones later for an FAQ, etc.

That and there's a few that need restoring for the heck of it, most notably the "You know you're obsessed when..." and "HATS!" threads (both of which I have located some of already).
