More activity there, certainly. I frankly see more answers I agree with to playing and teaching questions-- of which there still aren't that many. It's mostly about gear there, too-- there are some cymbalholics people there, and I think a number of drum builders, asking questions about the sonic implications of a 1/2" washer vs. a 7/16" washer on a bass drum spur. General vibe here is easier.
Moderation is more conservative there, and here more contemporary, let's say. I think ownership of DFO has changed, for awhile the owners obviously resented having to pay to run it, and thought that a link to anything off site was stealing traffic from them. I had to have a conversation to put a link in my signature, the guy was that ilk of old fart who enjoys being unreasonable, wielding his awesome power unreasonably.
Neither sites' moderation has really kept up with current events re: political conversation or comments-- a certain movement has made a lot of things political that were formerly not political, which puts a lot of ordinary topics off limits, because that movement views them as politically harmful, and wants to impose a narrative-- which biases both sites' moderation to favor that movement.
