Because the underscore hack is for IE6 only.

This is rather outdated. Please, please use conditional comments. They are far, far, less likely to break things in the future. (As long as you don’t target future IE versions)

[...] Elements disappearing, layouts borked, forms not working correctly, these are all things that occur within IE version 6. IE7 is far better in its handling of rendering issues, but the problem is that people still use IE6 and you have to worry about them. The IE6 version of 9rules.com is a little ragged but it is about 98% the same.
