Guys, us as computer nerds/geeks/experts use either Seamonkey, Firefox, Opera, or some other browser that isn't IE (or Netscape). The general public believes that if it looks fine in IE than it's good. Lots of JavaScript is IE specific and only works in IE. Lots of things only work in IE. Does the ordinary Joe take the time to care if another browser is better. No! As long as he can go to the Windows Update site he's happy as a clam. We cannot force other people to use Firefox (or other 'better' browsers) just because we think it's better. I use Seamonkey because I like its web dev tools and I'm scared of the security flaws. Are most people who use IE web developers? No!
Some people/organizations have taken strides to not use IE. At Carleton University, everybody uses Firefox (even though IE is installed on the computers by default).
To an ordinary Joe, another browser is just a waste of hard disk space. Who needs Firefox when you already have IE?
So, in the end, use the browser that makes you happy...I just might try out that Crazybrowser 😉
