I just took a snapshot of the browsers used by the last 100 visitors to this site. Microsoft's Internet Explorer won easily, with most using an older version like 8, 7 or (gasp!) even 6. Here's a pretty chart for you.
For those of you using IE by choice, I'm curious why. I'm not trying to be a tech snob here, I'm sincerely curious. Is it because you've never tried an alternative browser like Chrome or is IE just your preference?
