Radar.net were one of the first to get a Facebook application running, so I had to check 'em out. I like it! They let you email your cellfone pix to their service, where they add 'em to a shoebox for you. Then you can add "friends" who are always allowed to see what pictures you've go on the system. Also, for each picture, you can have the service email photos off to anyone you like ... and of course when you send a picture, they make it easy to invite the person as a friend.
