As the title suggests, what do you think about noindexing forum threads with no replies??
We do it here once we got hit by Panda the first time around, but then we recovered, and now we're hit again, and I'm wondering if it's a good idea to remove it.
We were doing it because I would classify those pages as "thin" pages because there's no response to the question being posed. I hate doing a google search and ending up at a page only to find that the question I have is there but no solution.
Then again, perhaps if smart people stumbled upon the thread as a result of a google search, and they knew the answer, they might be inclined to help the person out. Maybe it will foster more responses??
