Radar is a new mobile photo sharing application – but unlike its rivals, itâ€™s designed for sharing among a select group of friends. When you sign up, you get a unique Radar.net email address to send your images to – you can then invite friends to view your pictures and comment on them. You can use Radar on the web, or view the mobile version on your cellphone.
At a time when everyone else is building wide open, publicly viewable photo sharing applications (eg Where.com), Radarâ€™s strategy is an interesting one. While thereâ€™s definitely a demand for less public sharing, these services will surely experience slower growth: if your users arenâ€™t posting images from your service, creating blog widgets and offering free promotion on MySpace, itâ€™s more difficult to build your userbase. Yes, new users will be referred by their friends, but that seems much less efficient than web-based viral marketing ala Flickr and YouTube.
Image quality and network speeds will only get better. If radar continues to grow and innovate their potential is huge.
