Too Many Geo Announcements from SXSW
Feeds by Location
SuperFeedr will pass a geotag through its feeds (such as those tagged in Twitter) or if one is not present, it’ll add one. So, in time, you could ideally, subscribe to RSS feeds by location.
Brightkite GroupText
The free, “your friends don’t have to sign up but you do” app uses SMS to send a group a message - with location.
Brightkite Check.in “One checkin to rule them all”
The idea you check in once and the app (not yet released) sends it off to Foursquare, Brightkite and perhaps others. Gowalla? Unclear if it will be there since its API is currently read only.
