Most of the old forums outside of GD were graveyards even before the move, and GD was probably 95% shitposting anyway. I find myself spending less time on the new forums than the old ones, yes, but that's because it's a lot easier for me to find what I want to read, post what I want to say, and get it all done and over with compared to the old format.
And honestly, if the way a forum is laid out is enough to stop someone from sharing their opinion, then it probably wasn't that important to them anyway. If they cared, they'd post.
