Maybe all the threads about the price of bitcoin going up/down/sideways should be put in the TRADING board, since the price is all about trading?
And this topic should be moved to 'Meta'.
There just needs to be a little more hands on moderation for better thread placement. But I mean, technically almost anything could be Bitcoin Discussion, so maybe delete Bitcoin Discussion, yes this forum, make 4 or so more subforums (Bitcoin Marketing/Media, Bitcoin Theory, Bitcoin Love, and something else), the end.
People will be forced to keep their Bitcoin related discussions more focused into established Bitcoin subforums and the newly created ones, people can vote for what is important as the new subforums. Anything else is Off Topic, which on any forum is the dumping ground, but that is basically what the main forum here has become. I think this is a very possible solution too.
