it's a pretty tight community. the irc channel is intelligent and it's a lot of BSD people. also it's invite only so it keeps out a lot of the riff-raff. if you invite someone and they up up being a dick they are linked to your account and you get bitched at

It's meant to be Hacker News but less broken because of a smaller, less elitist community and downvotes are public. I may have to revive my account as HN has gotten less stable lately. Lots of downvoting for no good reason. Feels like the community is more rotten these days
