I’m checking out Joe Friend’s work to make Word 2007 a good blog post editor. So far what I've noticed is that setting it up was harder than I expected, in part because in order to find the Metaweblog API for blogs.msdn.com I had to RAS into corpnet over the weekend (always a wonderful experience) to get to the internal documentation page. Then there was the error message that kept popping up when I tried to publish the post to blogs.msdn.com telling me that I had put in the wrong password. But after some fiddling around, I got it to work. I can even round-trip (which I did with this post).
As always with beta software, caveat emptor, but so far I'm liking Office 2007 beta 2.
