Whilst I concur with the opinions expressed so far, I don't see how this can easily be done. I have seen several times an effort to have a single thread relating to questions on a specific plane. These threads can get quite long and that is part of the problem.

People who can't be bothered to trawl through 20 odd pages of a mixture of information, opinions and general banter end up posting seperate threads to answer specific questions.

It can't be be helped, this is a discussion board after all, and each thread is just that, a discussion; nothing more. Merging two entirely seperate concurrent discusion threads on a similar subject will only serve to confuse further.

The only way to create a meaningful resource from this is to take all the threads and extract the useful information and place it into an article. This then raises the issue of what to include and what to leave out. This would also be a lot of work to do for every useful subject that comes up for discussion....
