And Twitter of course. You'd have the best chance of success if someone could have a feed of everything they already read on Twitter, with other sources seamlessly integrated in. Perhaps even have the browser fetch all the data, without going through a server, using each platform's embed code. You'd miss out on discovery, and need to know which channels to subscribe to, but I see that as a plus.
