Martin Reed wonders if you should invite your friends to join your online community?
Friends, he rightly reasons, have a vested interest in your success. They're more likely to help you out and get the community going.
I still wouldn't recommend it. Instead, find the first 10 to 20 people you would love to have in your community, and become friends with them.
By the time your community goes live, you should feel more than comfortable about inviting them.
