Well Seth
(Seth Godin) you did it again....Great post today....And quite frankly, I am guilty of attempting to be everywhere on every social site. Below is a great quote...Read the entire blog post at his blog. You gotta go get his new book
Tribes: We Need You to Lead Us. Find it cheap on Amazon just click on the link. I am reading my copy now.
"If you have a presence on twitter, squidoo, blogs, facebook, myspace, linkedin and 20 other sites, the chances of finding critical mass at any of them is close to zero. But if you dominate, if you're the goto person, the king of your hill, magical things happen. One follower in each of twenty places is worthless. Twenty connected followers in one place is a tribe. It's the foundation for building something that matters."
