Go Brent, go! I can't wait for 1.1. Looks like it will be smashing!
About the weblog editor, here's the deal:
It's being overhauled, top-to-bottom, for the next release of NetNewsWire. It will be quite different from the current weblog editor.
The goals are:
To make it easier to use and more powerful. The user interface has been completely re-designed.
To support more weblog features than are currently supported. (Things like Movable Type keywords.)
To make it a better text/HTML editor.
To fix a bunch of bugs.
To make it scriptable.
