I know a lot folks still don’t get this whole RSS thing and that’s because, well, it’s a tad confusing.
Part of the problem really is the RSS isn’t a thing really, it’s more like a concept or a tool. What you make of it depends on a lot of things. So, RSS is a lot of things.
Yahoo recently put together a great little primer for RSS
I’d keep on eye on Yahoo as they eventually plan to put a Google AdSense type of offering together.
The more things on the Internet change, the more they get interesting!
