Oh, nothing much really.
Just every security hole of IE6, plus a few new ones for good measure.

He IS using IE there! Narf!

The site is pretty sluggish. No doubt from the legions of hardcore, fanatical INQers desperately trying to push EG’s popularity and ranking way up.

I also had it hang on me once (the page was unresponsive). Used my back key to get to the previous page and all was well again.

Does not seem to be terribly well indexed - it didn't find one entry from my blog (sniff, sniff) despite other search engines having indexed it without me submitting it.

You can skin firefoxy to look like IE, but that's just as blasphemous!

Call me a n00b, a fanboi or just plain daft, but what is wrong with using IE7? 

Not that I do mind you, I use Firefox, but that's because IE6 is rubbish in comparison, and it's now just habit to use Firefox.

I LOL when I saw you using IE.

Are you reallying using IE there?
