Internet Explorer 7 doesn't support HTML's
q element. This is rather annoying, as I've been using it heavily for marking up quotes - on browsers that do support it, it produces nice language-sensitive quote marks. I could understand this if it were an ancient proto-IE, but why does the latest version not support an element that's been in the standard since 1999?
I'll have to go edit old posts and replace
"...". Of course, Blogger's search helpfully ignores HTML tags, so I can't find them that way...
