Blizzard have just unleashed The Armory on an unsuspecting world, a searchable database of characters, guilds and arena teams. While much of the same information is available in-game using the “Inspect” option, The Armory also includes things like talents and trade skills (apparently… it seems to be a bit overloaded/flaky, so I haven’t quite got a character sheet up yet). Reaction on the forums is mixed, strangely enough (I don’t think you’ll be stunned to learn that many posters consider it “an outrage”), but personally I think it looks great, and could be really useful for guilds.
(Incidentally, for those of you who may, perhaps, be at work, with, say, a firewall that blocks “Games” related web content… maybe the firewall rules haven’t been updated to block The Armory yet. Not that I could possibly condone browsing it when you should be working, no.)
