We were talking about this way back in 2006 (and probably before, but that’s when I started taking notice as the social web started accelerating) and it’s good to see that guardians of the web like Dave Winer are still hard at work thinking and talking (and making apps) about this:
Create systems that are ambivalent about the open or closed web. If I create a tool that’s good at posting content to Facebook and Twitter, it should also post to RSS feeds, which exist outside the context of any corporation. Now other generous and innovative people can build systems that work differently from Facebook and Twitter, using these feeds as the basis, and the investors will have another pile of technology they can monetize.
Go read and use RSS.
