The folks at wordpress.com, bless their hearts, introduced MX support for Google Apps locally. Without getting too technical, it was previously impossible to have polytropos.org mail via Google and also redirect the url to the new blog home without paying someone for hosting. Now it’s possible.
So the old url for the blog is working again. And if you missed the fact that it changed and haven’t been here in a while, don’t worry, you haven’t missed much.
