We have a pretty good crowd here now. I think that most of our friends would also be a good crowd, and most of the annoying 14-year-olds wouldn't be our friends. And this didn't cripple the growth of Livejournal at all. You only get one invite a year, but you get it immediately on joining. I invite you, you turn around immediately and invite someone else, who invites someone else, etc. The 1/year rule is meant to make me careful about who I spend my one invite on.
