Well, the antidote would be for us Americans to post more stuff about "our" music -- right! You're from Chicago, aren't you, MG? So you should know the drill: Vote early and vote often!

Seriously, though, I've noticed the same thing. I first stumbled across Mudcat years ago, when the DT had first been moved here from Xerx PARC-- at that time, this was a prediminantly blues-oriented site, with mostly American participants. Over the years, I would peek in very occasionally, before joining up about two years ago. There's been a steady growth of "overseas" participation; not just the British, but Irish and Aussies and various others -- even an Icelander!

From what I've been able to observe and deduce, the Brits are closer to each other geographically than the Americans, they seem to have more clubs and events in which to participate, and more of them find ways to meet in "real life." The result is that they've become a tighter-knit group, in general. So be it, and more power to 'em.

I think that if you disregard the purely personal messages and the announcements of various events in the UK (festivals, club nights, etc.), the number of *musical* posts about US vs UK folk music is closer to equal.
