Sorry to be late to this party! We actually have a google group called Akratics Anonymous, described at http://blog.beeminder.com/akratics which has some Less Wrong folks already. We'd love to have more.

Also, thanks so much for the patience with Beeminder! I've been getting tons of encouragement and enthusiasm from the LessWrong community ever since this post in 2009: http://lesswrong.com/lw/am/how_a_pathological_procrastinor_can_lose_weight/

I've now added everyone who got on the waitlist with invite code LESSWRONG. We're getting close to public launch so I wanted to invite any other LessWrong folks to get a beta account first: http://beeminder.com/secretsignup (no wait this time!)
