Twitter recently announced that it has cut-off their firehose data distributor DataSift. This move echoes Twitter's controversial 2012 API changes which restricted the Twitter client ecosystem. There is much speculation as to whether this latest announcement is an attempt to control the tweet analytics space and whether or not this is behaviour fitting of a platform provider.
Ajax Control Toolkit has been updated to support jQuery and includes a new Twitter control which takes advantage of new Twitter API. It also includes an improved documentation which describes the usage of ToolkitScriptManager.
