I just finished culling through about 200 sites and folding most into the resources and portal pages. I stored these up on del.icio.us over the past two years while writing the new edition; now they’re in (or deleted – amazing how quickly some of these sites go away).
The references page is also corrected, as some links and whatnot were dropped by my original perl script. We try to not repeat any articles listed here on the resources and portal pages, which is in one way unfortunate. Really, the references are the bulk of the serious resources.
I now feel like the site is officially open; please do send on any great resources that we’re missing (or just put them in the comments here).
