I'm searching for some common ground between the twitter-like systems, a basis for interop, a common API even. We had that for the blogging layer of this onion, something called the MetaWeblog API. All the popular blogging software supported it. And that meant you could write once and publish to many places. And you could write the script that did that in an afternoon or two. We started out with simple systems and the best of intentions. There's no technical barrier. And we could do it in a few weeks at most if there was a will to do it
