We wanted to let everyone know how the alpha invites are working.
After some thinking before we started sending invites out, we decided that it would be more useful for everyone if we gave out invites at a slower rate, but gave more invites to those invited. If we gave one give one invite to all 6,479 backers the first day, that would not be helpful for anyone. We wouldn't be able to see how people were really using Diaspora, and people would not be able to have their real friends on the site.
Instead, we started giving ten invites to a smaller number of backers, and increasing that number as we can handle it. After all, a social network is only fun if you can talk to your friends.
We are working as fast as we can to get invites out to our backers, and rest assured we are not sending invites to people who did not back us before people that did not. If you did see someone who is on before a backer, we did not send them the invite, one of their friends (who was a backer) did.
