IE 7
 

I just discovered that my site looks like crap in IE7 :)
People still use that browser ?

Last month I had about 6 percent of my visits from IE 7. Don't know how that compares with everyone else. Heck there are still few out there using 4.0 some people are way outdated

Looking at half a dozen of my bigger hit domains I show an average of 9% IE7 and 6% IE6

I just checked and looks like IE6 is about 4% to 6% depending on what site I'm checking and IE7 is from 6% to 25% but the one site in question is exactly 6%
Not much but still small numbers adds up. JR thanks for stats.

54% of LOR surfers use IE - 15% of those use IE7 (75% are onto IE8)

IE7 users: on average 4.5% (11% on one of my sites)

Be sure to also check if it works in Firefox 2. I still get a lot of visitors who use that one.
