It's a little thing (and truthfully, there's probably not much there that you really need to know anyway -- if you're away from a WoW client, obviously you can't log in even if your realm is back up). But you never know, someday when you're thinking about World of Warcraft, far afield of your installation, and really need to know what Blizzard has to tell you, it could come in handy. Definitely earned a place in my bookmarks, just in case.
And having it in quick and easy online text form means we can script it to go elsewhere, right? Anyone want to try hooking a Twitter account up to this thing?
