In the early days of RSS, we had the idea that instantaneous updates would be the next step. That was 2001. It took a little longer than we thought, but now with "realtime" as the Next Big Thing, it's time to reboot all that lovely stuff.

If it works, it'll be a bootstrap. That means at first the results will be a few sites pinging each other and updating in realtime. If it gains traction, it'll get support from a lot of tech and media companies. It could happen very quickly.

One thing's for sure -- we'll need implementations in every language and runtime. I'm doing mine in the OPML Editor, of course. But just think of that as a reference implementation. I think the really scalable versions will be in Python, PHP or C.

Also thinking about using Amazon's SimpleDB to store the graph. We'll see..
