I'm posting this from Facebook using BlogIt, an application written by Six Apart. You might know Six Apart from such blogging tools as Movable Type, TypePad, and Vox. BlogIt allows you to post, from Facebook, to a blog at any one of those three – or at Blogger, or at WordPress (self-hosted or .com), and so on.
BlogIt allows you to send the same post to a combination of such places, as well as to your Facebook mini-feed. This post is just going to Changing Way and to my mini-feed. That would be a good thing if I had friends for whom Facebook is the web (just as AOL was the pseudo-web of their parents), and I wanted to make sure that they saw my blog posts. I already do that, and do it rather better, using the WordPress.com FB app, but of course that's WordPress.com-specific.
Even so, I don't see why or how BlogIt could be the start of something big. And now I have to go to WordPress.com to fix this post, since BlogIt doesn't let me categorize or tag it, and I'd rather use the post editor there to put in links than have to type in the html here.
