Part of me thinks that's great - the reader could benefit from the different views presented within the thread. On the other hand, It might take you a while to look up all the threads - assuming you didn't simply add to it over time. The nice part of a FAQ by itself is that it's focused - the reader wouldn't have to read through all the extra things in a thread if they didn't want to, and the entire thing could be printed out easily. I think I slightly prefer the "link to the threads" option a little better, but both ideas have positive aspects.

Before they made me they broke the mold!
