Write a Getting to Know You email, with questions for your friends to answer. Send it to lots and lots of friends, especially those with whom you have lost contact but still like. Old coworkers you meant to keep up with. Some silly questions, some serious, some open-ended. Not toooo many, but enough to open dialog. Learn something about your close friends you didn't realize. Get to know people more deeply. Find some pain of theirs, hug them (even virtually), lend some support. Open channels with people you haven't talked to in years.
