I like writing and surfing in IE better than NN because I get fewer errors and less crashing. The later versions of NN became so strict regarding acceptable code that it wasn't fun to write for the browser. Remember that the bulk of Web pages are written by Weekend Silicon Warriors. It's a bad sign when I get e-mail saying the page looks great in IE but won't even render in Netscape. The funny thing is that the problem is usually something minor, thus very hard to pick out.
Giant mistakes are easier to see.
People got tired of being wrong a lot of the time. IE seemed created more for the Weekend Warrior. NN seemed created for the professional programmer. Now, I know this will prompt a great deal of e-mail, saying that people should write like programmers and they should be held to strict parameters. I actually agree, but let's be honest.
