The Agrinautica

30in30, although it's barely coordinated there and the community is in a bit of disuse. The way I invision it, esp if a large number of people do it (which I think would be awesome), is for everyone to for themselves decide which other participants they want to keep track of. I've established the livejournal of arrrghonaut, whose purpose is basically to coordinate everyone I know is participating. So basically, go ahead and join 30in30 and if you end up doing it arrrghonaut should keep you abreast of who else is doing it and such and such.
