Mozilla is built to be compliant with W3C specs for HTML, Javascript, etc. If a page won't render correctly in Mozilla (ergo NS 6 and 7) it means the site was built specifically for IE. If the site uses IE specific features and not W3C standards then you shouldn't expect Netscape to load it properly. What Netscape is doing is saying "WRITE TO THE F%#$ING ACCEPTED STANDARDS!!!!" in a more polite way. Many users have been bitching about this for years. The Mozilla hackers are more concerned with standards that'll work consistantly on all supported platforms, not locking in developers.
