Since I live to state my opinion, I'll weigh in, even though I don't really have a production blog. I think the one thread idea has always been shit. A catastrophe. A total mess. A waste of time to wade through.
I would have voted for a link trade subforum or move all of the link trades to the board's main link trade forum. (It's not as if link lists or TGPs have their own separate link trade forum.) Link trade threads do clutter the the blog forum, but a single thread becomes a confused mess and is probably far less productive for gaining trades.
