(Not about symbiosis, sad to say. Or maybe it is.)
In an effort to run less software myself, and having decided that WordPress was the right way to go for this blog, I have moved from a self-hosted WordPress instance onto WordPress.com. (A hundred bucks a year was a small price to pay to not have to be personally responsible for taking updates every time someone finds a security hole in WordPress, which is sadly often, and it will cut down on the amount of time I spend spam-whacking too.) All of the content should still be here, and all the links will hopefully continue to work.
Let me know if anything does break in the comments or at firstname.lastname@example.org.
