If you are as optimistic as we were about Twitter's location features, you should be downright giddy now. Twitter has acquired the company--and staff--behind one of the most innovative mapping-related APIs. Mixer Labs' GeoAPI , previously known as TownMe, hosts your geographic data and allows spatial queries such as "find the closest location" (for more see our earlier TownMe news coverage and our TownMe API profile).
In less than sixty days since the private beta release of its API, Portland-based Shizzow has now released its API (our Shizzow API Profile) to the public. If you are not familiar with Shizzow, it is a location-based social service that a small, yet dedicated, team of techies built with the goal of helping you build quality relationships through face-to-face interaction. Sharing some similarity with Yahoo!'s Fire Eagle and other location based services, Shizzow functions as a geo-location service that allows users to send "shouts" out of their location, which are subsequently passed on to friends through updates in several mediums. Originally limited for use by Portlanders, Shizzow recently went public in conjunction with the public release of their API.
Popular location-based social network Foursquare quietly made the long-teased new version of its API publicly available Tuesday. The changes, embraced by its developer community, include JSON-formatted responses and OAuth-only authentication. Even though the new API is characterized as in beta, the company has also deprecated the previous version, announcing it will no longer be available by the middle of next year.
