Whenever you snap a picture you want to share, you send it via e-mail to your Radar account. It appears immediately, and everyone you’ve invited as a friend can see the pictures and comment on them—either online or on their phones. The best way to use Radar is to download the application to your phone (it just added a custom iPhone app today). Whenever you log in, you see a stream of thumbnails of every picture you and your friends have posted.
The commenting interface is pretty slick (you can plug it into AIM for instant notifcations of when a new comment has been posted to one of your pics). It the key to Radar because it turns each picture into a conversation starter. This only works, of course if you A) have friends on Radar, and B) they post pictures on a regular basis.
