Matt Webb is at HyperText 03, a conference in the UK (inconveniently (or conveniently for AZ) just a week and some before we're due to be there).
From the conference outline I reviewed before (the site is presently timing out...), it looked to be fairly interesting, with a wide range of speakers within the topic.
Matt's been gracious enough to put a bunch of live conference notes online. Looks like more Hydra^WSubEthaEdit action is taking place....
