Radar

Radar was a bit of a niche photo- and video-sharing site that would let users take and upload media from their phones or computers. On the mobile side, you could use its app on just about any phone either through an app, or the special upload e-mail address it would give you upon sign up.

One very unique aspect of Radar was that it was a private affair. You shared photos only with the people that you wanted, as opposed to the vast majority of other social photo sharing services, which would put everyone's shots together into one big stream.

Over the years, Radar began to tie into other sites like Facebook and Flickr so that you could browse and post to these places. But with those two sites also offering increasingly extensive privacy controls, the reason for using yet another photo host had most people scratching their heads.
