Actually... I was right there with Glirdy when I first saw this thread... thought it had something to do with physical (erm... yeah...) speed. Possibly because I was waiting inordinately long for the next subforum to load while I waited.
But a lack of activity?
Well... maybe...
Speaking as a getting-more-involved RPGer, I feel like things are really moving, but I can see what you mean. But I wouldn't worry. Forums go through fast periods and slow, and strangely (or naturally) the time when people seem to have the least amount of time to spend here is... the holidays.
Only a few numbskull, no Life- diehards like us still stick around.
Besides... what is talking about it going to do? You can't FORCE people to post. Though you CAN blackmail them...
