If you're one of those people that always need to tell people exactly what they're doing, then Radar.net is just the thing for you. Essentially a social group made up of people you invite, Radar lets you email or MMS pictures to it which gets spread to everyone else in your network.

So if you want to keep up with your friends and family from the office or on the go (you can view pictures on cellphones too) then give Radar a shot. It's of limited usage right now, but could be cool if you have a specific need for it. – Jason Chen
