A new and improved Twitter API
This is what they cite as the key benefits:"A cleaner API that's easier to use, with new developer features like the ability to specify which fields get returned, or retrieve more Tweets from a conversation within the same responseSome of the most requested features that were missing from the API, including conversation threading, poll results in Tweets, pinned Tweets on profiles, spam filtering, and a more powerful stream filtering and search query language "I really doubt this is what developers have been yearning for in a revamped Twitter API. Previous APIs provided plenty of functionality, it's just that too many of us were burned by the ever-shifting policies around API use. I personally went from envisioning Twitter as the social data pipeline of the web to vowing never to touch it again within the span of one year. I can't believe this announcement wouldn't touch on policy and developer relations at all.
