Ask N.YC: Is there a public, high SNR robotics list?

I'm looking for a high signal-to-noise robotics list to lurk on. Sometimes these things are not widely publicized, to keep the quality high.

I'm thinking of something of a similar quality to the arocket list: http://www.arocketry.net/forum.html

Of course, I'm presenting any potential responders with a dilemma: to publicize or not? I'd just say that the current n.yc audience can probably be trusted not to decrease the SNR of such a group.
