On Tuesday, social media giant Twitter announced that it is buying Data as a Service (DaaS) provider Gnip for an undisclosed amount. Gnip, which is one of several companies that sell access to the firehose of the content posted on Twitter, was founded in 2008 and today offers data from a number of popular user-generated services in addition to Twitter.
Popular social check-in service Foursquare is going through some changes, and the most important of those is that the old v1 API is going dead, as we've known since March. Older apps, especially abandoned ones, will stop working then, as will any newer app that hasn't yet upgraded to the new API.
Facebook is starting to approve additional "actions," verbs that let users go beyond Like. Developers can use Facebook timeline actions via the Facebook Graph API, but only if approved by the social network. Social shopping platform AddShoppers received approval for "want" and "own" and even has some Like-like buttons for those actions.
