I recently joined LinkedIn (http://www.linkedin.com/). Seems like a good way to get hooked up and stay connected. See my public profile at:

Join yourself, you might be surprised how many people you know that are on Linked In.

Yeah, but consider this. Sites, like this one, paint a much more interesting picture of a person than anything you can get from a service like LinkedIn. At least for me, I’d be searching my contact list (either in my e-mail client or cell phone) and my syndicated feeds before trying to find people on LinkedIn.
