You, sir, are very correct. Remember how much fun we had recently with project905? That originated in /b/, yet as a board we came together and did our best to further the game along. I remember the same thing happening with Trinstod.
My beef with the state of /x/ is that ALL of /b/ seems to be coming here. I can't speak for the rest of the boards on 4chan, but I believe that /x/ started going downhill with the flood of newfags that arrived when 4chan was made "public," G4, etc. The old spirit of /x/ is obtainable, and I long for it as well.
