I've already said I'm quite happy to believe you are growing. The internet makes all kinds of crazy ideas easy to spread and if crazy ideas are spread then as you say 'x' percent of people may come to believe them.
I happen to think that x is very low in this case. Let's say a million people in the UK come to believe this. That is, objectively, a LOT of people. But percentage wise...I'd still be unlikely to know many people who believe it if that were the case. I'd suggest the number right now is orders of magnitude less than that. Now, admittedly, you may have a better feel for the numbers than me. But the number of people who attended the conference, the sort of people speaking and the amateurish feel about the whole thing makes me believe you're somewhat deluded if you think that you lot are on the march and are having a big impact.
I sympathise to an extent, I'm an admin on another board which was actually pretty popular back in the day - you don't publish your post stats here but certainly in the upper fora it's what, maybe 50 posts a day? The board I run in its pomp got about 2,500 posts a day, we were quoted in a couple of papers, we had quite successful meetups and I did feel some giddy excitement at the thought that we might grow and grow. Didn't happen of course. But my take on this is you're enjoying your 5 minutes of "fame" a little too much and getting a little deluded about how popular this movement is becoming. Tom is a bit more realistic (see my sig).
But hey, I guess if I'm still here trying to teach Tom about perspective in 5 years time then we'll see who's right...
