Then when I looked thru the site, I was quite astonished that there was an entire board dedicated to my particular fetish.

And with actual useful information, too.
As an aside, its interesting though that it seems every 6 months or so the 'main actors' on this site 'turn over'. I joined last october or so, so thats what, 7 months ago. I had a rush of activity for 6 months, and its tapering off now as I tried out and then found the boards and switches I like. But as my activity level drops off, I've noticed a lot of people I was talking with on this site have also faded away quite a bit, replaced by new names, faces, personalities.
Maybe, aside from a few stalwarts, the turnover on this site is about 6 months (which is about how long it takes to experiment with boards and switches I think). But whats nice to see is that regardless of that turnover, the new blood coming in so reliably makes this still the premier site for keyboarding in the u.s.
