I'm seeing X-UA-Compatible abuse everywhere these days. It seems most of the big sites I look at have decided not to give the IE8 team half a chance to iron out their bugs, they've all simply decided to close their eyes and slap on a "behave like IE7" instruction instead. Guess if this is going to cause compat problems down the road when all non-IE browsers are forced to look at the META tags and figure out if they should be bug-compatible with IE7, 8 or 9 for any given site.. 😦
Here's a funny offender: adobe.com insists that if I'm going to show their "flashAbout_info_small.swf" animation correctly, then ..

Beautifully compatible, no? Thanks for the X-UA-Compatible hint, I would never have figured that out on my own!
