I agree with it, too. I don't see the big deal with myspace or facebook, in a big picture kind of way. Now that people are on it and have built out some social graphs, they're asking "now what?" and there is no good answer. What is the big itch that facebook scratches?

The demand for the fast, free flow of information about your friends' and acquaintances' lives and events, not only to tell you about who and what you already know, but about who and what you'd like to know; And it works.
