LinkedIn (http://www.linkedin.com) is a popular BusinessNetworking site (their main, and much smaller, competitor is Ryze.com) and gaining lots of acceptance recently.

It is a lot less fun than FaceBook, but then again, its not meant to be.  Hmmm... when did it happen that work is not any fun (see FortyHoursVsFun)?
