Om Malik's Broadband Blog: My Network, My Way!

The question I have is: why the F**K should I share my network of contacts with these commercial entities. They are like BlogSpot that does nothing for my brand equity and in many ways chews me out after making the network connections. Thus what I want is a "Movable Type" of social networking. Blogs took off because it was about one person - me. My social networks should be of my making for me. Lets figure out a way to cut out the middlemen.
