Brightkite is a location-aware social networking app for Android, iPhone, and now BlackBerry that lets you share photos and notes at certain GPS coordinates both with your friends and to the community at large. Using the service requires you to occasionally “check in”, which might be a pain for those who are used to automated location sharing like we see in Google Latitude, but it does open the doors to those who don’t have integrated GPS in their phone. The interesting thing about the BlackBerry app in particular is that it was built by a third party using open APIs, basically making myKite a homebrew job with an official seal of approval; good on Brightkite for supporting the developer community like that.
