The fuck? IE was absolutely dogs hit performance wise not to mention their non standard support of Javascript (JScript) was horrible. To accommodate IE you needed VBScript to perform well so basically a whole different site.
Netscape was always better but once they shoved IE on everyone you were left with doing 2 sites for a smaller percentage. Most corps flat out wanted IE only and VBScript / ASP and cut out the Javascript. Even then you sometimes had to do things ass backwards to make it work on IE.
I learned that lesson with experts-exchange even before stack overflow. All sites will be bought out and enshittified.
