http://www.facebook.com/krypted – Facebook, like other social networks before them now allow you to sign up to have a name, or handle, that will follow you and allow you to quickly find friends provided you know their unique name, etc. It seems to be a bit of a scramble and names are filling up fast, so I wouldn’t wait for long. It’s easy to do, log into your Facebook account and there’s a box staring right at you asking if you want to go ahead and set it up!
PS – Thanks to Kevin for reminding me when I got off my flight!
