At some point over the weekend, I'll be moving The Metaverse from Typepad to a new Movable Type 4 install. This means that it won't be available for up to 24 hours, assuming that everything goes well.
If you're subscribed via FeedBurner, you shouldn't notice any interruption at all.
UPDATE: Belay that. As you'll know from my main blog, the Movable Type install just got too much, and had too many problems.
