It's probably because in this version of the thread, certain posters have felt free to post far more often. But you might say, "Wait a second, Farty! Wouldn't that mean the thread's post count should be higher?" No, because the inane bullshit that they constantly spew means the members who would normally post shit worth reading end up skipping over pages of the thread. With nothing to read, they feel no need to post. However, the morons do reply to each other with more of their insipid drivel, creating a self sufficient ecosystem of idiocy that feeds off of unfunny gifs, unnecessary diary updates, and terrible opinions.
But hey, it could be worse. We could still be in the PSN thread in the Deals forum.
