I’m playing around with Tumblr some more. The RSS feed should redirect automatically. Web version is davextreme.tumblr.com.
It’s a very polished application. As much as I like being able to tweak everything on a self-hosted site (and I do), I like the ease of a third-party service. What it doesn’t have is an import feature, so I can get my Movable Type posts into it. Batch post edit would be nice. But I’ll play with it a bit and then either point my domain there or move the posts back to here.
