Magic Numbers of Social Networks

25 - suppose you never invite anyone to be a friend on your social network (hyves, facebook, linkedin), but you always accept any invitations from people whose names you recognize. Then this is the number of invitations that you need to accept to reach critical mass and a significant increase in membership. (you'd go from 10 to 25 invitations in about six months, but from 25 to 50 in about four weeks)

199 - number of "friends" you have on your social network, before you realize about 192 of them are sad, and you move on to a new social network and start over.

[guys... I do seem to have a plaxo account, but I simply don't remember how to log in!]
