I've seen companies publish errata as pdfs of the effected pages, with corrections included. I really would have preferred if WotC would do that so I could tape those into my books instead of having to cover the pages with postits.
Also, most of the errata I was really looking for isn't here, like clarification on how multiclassing into ranger works for paragon paths, or how wizard spell preparation works, or a fix for Avalanch of Blades.
Still though, I'm impressed with how quick it is. It's a great start.
