Under certain circumstances (eg intranet sites), IE8+ falls into "compatibility" mode. This breaks all kinds of CSS (eg menu bar) and makes it right impossible to use some JS stuff:
http://drupal.org/node/1991774
The fix is to include
<meta http-equiv="X-UA-Compatible" content="IE=edge">
right after the tag in html.tpl.php.
If it's inserted later, it might not work.
For background, please see:

Diff added.
N.B.: This affects all IEs > 7, even IE10.

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> would be better choice as it will enable chrome frame if someone has it in addition to forcing IE to using newest mode.

I got pinged on IRC about this issue about a month ago (I haven't been going on IRC much lately so I didn't see it until now!).

Need anything from me here still?

How can we establish this as default?

Chrome Frame is being discontinued as of January 2014, so perhaps not worth adding any specific support for it: http://blog.chromium.org/2013/06/retiring-chrome-frame.html

I believe this was fixed already in #1203112: Add X-UA-Compatible HTTP header
