Linked In is Like Email; Facebook is Like IM

I've never been a fan of LinkedIn (I'm not a "head hunter," and it undoubtedly is a useful tool for people who do that for a living). It might be a nice utility for updating contact information for a small subset of the people you actually know and communicate with. Beyond that I've never had occasion to use it.

Facebook seems like a better version of LinkedIn, though. I was able to get my son's new address when he went back to NYU without using LinkedIn. To be sure, the information wasn't pushed to me. I had to go view his Facebook page. But I got what I needed without emailing or calling.

So why is LinkedIn like email? It's a tool "older" people use for work. Why is Facebook like IM? It's a tool "younger" people (and increasing numbers of "not so young") use to keep up with other people they actually care about. In some important ways, IM also is a "richer" experience, as Facebook is.
