Many thanks to this week's RSS sponsor, radar.net. Radar is a service focused on easy-but-powerful mobile sharing of photos; basically trying to make it easy to take photos from your cameraphone and share them with friends, either on radar.net or a number of other sites like Facebook, Twitter, and Flickr. (If you'd like, you could call it a Twitterized Flickr.) Although they are currently promoting their iPhone app and the service's recent integration with Flickr, they also have versions of the Radar app available for other phones, including the Blackberry and Sidekick.
To check Radar out, get the Radar app from the App Store and sign up for an account at radar.net.
