Breakfast topic: What have you learned from the Armory?

We've got some great tools for guilds. We've got generated signatures, lots of Legolasses (and Legolads), some liars revealed, and even the worst players (that last one is from an official Mike Schramm Troll Post (TM)(C)).

So in the two weeks since it was introduced, what have you learned from the Armory? Have you figured out something new by checking out someone else's spec, or learned something about your guild from theirs? Have you gotten a good tip on an item you can't live without, or found one that you later asked a guildie about? Have you checked out a "famous" WoW player, or checked how many players have the same name that you do?

Blizzard has put one of the most comprehensive tools online for any MMORPG. It's only been around for a few weeks, and it's only in Beta, so we're apt to see more functionality arise for it yet. But here in the beginning, just what are you using it for?
