Once I’d worked out that a backup script had managed to overwrite some of the new MovableType files with copies of the previous version, things seemed to sort themselves out :-)

The new site design has some interesting features, in particular:

• Live comment preview.
• Live search.

Both of these are implemented using Bob Ippolito’s MochiKit, which I’m now a big fan of; it makes writing Javascript a lot less about tediously hitting the differences between the various implementations and a lot more about getting on with what it was you wanted to do.
