I've crunched the numbers, and there is a very clear drop off in stats. I'm not at my computer at the moment so I can't share them, but it is noticeable.
I suspect that it isn't a blip, isn't even static, but it's increasing over time, but I dont have the data yet to prove it.
Now that we don't need to worry about keeping our Regular badges, we don't need to keep reading and keep generating traffic for the site. Also, now that it's clear that the powers that be don't give a damn about us, we certainly aren't gong to keep coming here out of the goodness of our little hearts. And now that most of the communication between former Regulars seems to be away from the main site, it's ridiculous to assume that we're going to participate in something we don't have to participate in and don't want to participate in. The people who are being alienated are the most active members, those who generate the most activity, and who felt the least alienated earlier. The only reason most of us haven't fucked off by now is because this is more than a website for us, this is a community that we have all built together, and we would hate to lose it.
