We’re all for browser addons and extensions. But does any real geek or designer actually use IE7..?  Is it possible that a developer or serious web surfer uses IE7 as their “primary browser”..?

You would have to to warrant adding to it. And apart from site testing, we don’t use IE at all.

IE7 would be waaay down our list of preferred browser. Opera, FireFox, Safari and Maxthon would be booted up looong before we resorted to that.
