Those who have joined Tribe after December 2005 probably don't know that there was a huge controversy around the fact that Tribe began, on December 20, 2005, to censor "mature" material, saying that it put Tribe in danger of being shut down, thanks to the likes of Alberto Gonzales.

Tribe made significant changes to the ways in which people could find and join tribes, especially if the tribes featured "mature" material. Networks got closed off and privatized, and a lot of people left Tribe because they couldn't conscion the limitations that had been imposed on us.

Before that time, I tended to view "friend collectors" with a bit of scorn, but the changes Tribe made made it more difficult to form connections and networks, so I decided then that I would do as much as I could to help open new networks between people.

Since then, I have had a policy of accepting all friend invitations. I don't always keep all my friends forever, but I have kept most of them, even if we've never spoken since we became friends.

For a number of I don't invite everyone who interests me to be my friend, but I keep my eyes out for interesting people all the time, and there are a lot of faces and names that I recognize after being an active Tribe user for a year and a half now. And of course, if they make the first move, I accept all the time.

So if you want to grow your network fast, I invite you to invite me to your circle.
