I get all giddy when I hear there are new APIs coming out. APIs gives developers the freedom to express a level of creativity they might not be able to reach without APIs. Just think of all the current SEO tools out there that totally make the SERPs artistic. :) Seriously....
Danny Sullivan at the Search Engine Watch Blog posted an entry named New MSN APIs To Be Offered this morning. He describes that "MSN is to offer series of APIs for MSN Search, MSN Virtual Earth, MSN Messenger and MapPoint." At the MSN Developer API site it says "MSN Developer Center...Coming September 13th." So keep watching that page for updates. For a full list of features and information, Danny posted the excerpt provided by the MSN team at his blog.
