I really like the site linkedin. It’s got a nice professional feel to it and many of my friends and colleagues have joined so it seems like it’s kind of become a little bit of a defacto standard (for now, everything seems so temporary these days….)

They just added (or maybe i just noticed) a way to import your addresses from another account (google, yahoo, etc) and match up your contacts with linked in members. I really like this because they fixed something that I always felt was a problem. My addresses were already in another tool, finding people on linked in to invite them just became much easier and leverages the work I’ve already done building my contact list somewhere else. Chalk another one up for sharing. Thanks linkedin.
