It already works...
Winer on blog application interoperability;
"On this day last year I got My Weblog Outliner to post to Movable Type. In the comments I said release was just a couple of weeks away. But then Murphy swung into gear, and now it's a year later, and it still hasn't shipped. Damn. "
Actually, Dave doesn't need to ship - the Radio Outliner already works in a competitor's blog management application: Blogware. We've built a highly interoperable application that will allow users to use the widest possible range of tools in weird and wonderful ways that we haven't even figured out yet. Heck, you could use any or all of Radio's aggregator, Blogger's editor and MT's rendering tool to manage your Blogware. I don't know why you would want to - we offer the best of all of those tools anyways - but the point is you can.
We'll let others decide what the ultimate standards are - in the meantime, we'll just support as much as we can.
Watch. Think. Code. Launch. Repeat.
