I’m in the process of moving this blog. It is now powered by WordPress (rather than Typepad/Moveable Type previously). Although I have migrated all the content, links to posts may currently be broken – I’m in the process of fixing these, but it may take me a couple of days – please be patient!
In the meantime I think all the RSS/Atom feeds are working OK and you shouldn’t need to do anything if you subscribe via one of the feeds.
