[Darren] Someone needs to do a good, solid corpus-based statistical study on activity rates in the Morniverse. I'm sure it would make a good PhD topic. My impression is also that activity has declined, but it was less busy than now when I first joined eight years ago (bloody hell, eight years). In those early days, fresh with the joy of discovery, i can remember having posted the last move in every game on York and MCiOS, and being quite at a loss for what to do next once I'd done it. Especially on weekends. In retrospect this was a bit rude, but I was immature and callow even in those days. :) I find that nowadays I tend only to post in a small subset of games and even when bored am unlikely to stray into the others. Maybe other people have gradually settled into a similar pattern.
[Projoy] I certainly have settled into a similar pattern, though I'd like to think that's because I'm less obnoxious now. I'd say the most concerning trend is the seeming lack of interest in the game of Mornington Crescent itself - our one token game here, for instance, is crawling along quite pitifully, and Long Games all over the Morniverse have slowed to the pace of Jeremiah Snail, the 1956 All-Dorking District Champion.
I think that posting only to one's favourite games is quite normal; it's certainly my style, but it depends on how creative I'm feeling at the time, if at all. A good rule of thumb is that if you have nothing interesting, witty etc to add to a game then wait till something more promising turns up. There is increasing verbal incontinence and rule-bending simply for the sake of posting something. The whole thing is beginning to annoy me, and not just me, as I know privately. We could also do without those who post under more than one name, which is deceitful and sad. One has already been outed and I have a very beady pair of eyes on another one.
