The Word is 'Blogstreaming'

I’m drowning in blogs. Each of them are useful for updating a specific website or allowing me to sound off on a specific topic, but I need a one-size-fits-all solution. Currently I’m scattered over a handful of different mechanisms. According to this article, the word for what I’m trying to do is “blogstreaming.”
That is, I need to be able to use a single interface for creating my posts or articles, and then with categories or some other classification tool, and syndication or some other way of supplying content to multiple front ends, send the content where it belongs. I’ve thought that MT can do this, but I’ve been slow to get it going. Looks like RU might be able to do the trick as well. I think I need to learn more about RSS.
