Socialmod is a system to either automate or simplify your site's social content moderation. Its socialmod API allows for direct integration of socialmod into your site, making using their service far easier. Its service has been used for such high-profile sites as the BET.com awards, as described in its blog.
The Facebook Wall has fallen. Actually, didn't the social network lose the "wall" when it launched Timeline last year? Nevertheless, the Facebook API still had access to post updates (assuming the user gave the app permission). Effective immediately, Facebook is removing access to the writable wall, pointing developers to two alternatives that lead to less spammy outcomes.
Google has just introduced a new Enterprise Service, "Google Maps Coordinate", a web and mobile application that helps businesses manage and improve the efficiency of their mobile workforce. You can check out the Google Coordinate API here.
