Location-sharing service Gowalla is preparing to launch its long-awaited write API (our Gowalla API profile). The move could makes its platform as desirable as its main competitor, FourSquare.

ThinkUp -- the free, open source web application that captures your posts, tweets and other data on social networks like Twitter and Facebook -- has added support for Google Plus. Thanks to the the newly-released Google Plus API, ThinkUp now lets you download all of your social data from the major social networks.
