These are sort of extra-musical thoughts, but tangential enough I suppose.
I'm tempted every now and then to start a meta thread about roulettes. It's such a fascinating idea that I've never really seen anywhere else, but definitely is fun and promotes camaraderie and friendly competition, that would probably improve a number of other forums I've participated in or observed over the years. Many others here are familiar with then, even possibly jaded a bit, whereas I didn't start paying attention to them until just a few months ago.
Which brings up a related thought, that I'm in a weird position of being both one of the "oldest" (in forum years) members, lurking in and eventually participating in old DT forums in the 00s, and signed up on this specific board in '07, and yet one of the newest to this particular iteration, not rediscovering it until summer last year, so I have a dozen+ year gap of missing time.
