A VC: Linking In: Fred Wilson blogs about the usefulness of Linked In. Ev Williams also blogged about it today. I’ve never really thought much about it until recently and just kind of ignored social networking requests that came into my in box. But you never know — there could be some usefulness to it all. I thought it might be interesting to be able to have in my Linked In network some of the people that work in and write about technology. We’ll see how it goes.
