LinkedIn Leaps Forward

In the NYTimes today: At Social Site, Only the Businesslike Need Apply. Good overview on this 'businesslike' social networking site LinkedIn. I have been a member for several years, but only in about the last year have I seen a rush of current and former colleagues rush to join. A Facebook for the professional, but very careful to look like it is about the work. They are also starting to work more directly with corporations, in the past it was all about professional individuals. Lately I have started to use it as the only social network profile that I routinely keep up to date. Worth joining to keep up your own professional trajectory and connections to your colleagues.
