There's a freaking reason why Netscape is quiting the browser business! I've always hated using their browsers, although it is much faster on Mac's than IE, on an iBook POS I used at work during school, IE would slow everything down like crazy. Then again, the damn iBook was a POS too.
Their new 6.1 release was pretty good. And that was because they got with the program and made it compatible with HTML standards.
I've never coded for Netscape and never will, at work we spend half our time freaking figuring out how to get Netscape to display things right. Even the consultant we spoke with working on a parallel project was bitching about Netscape. Hopefully the Navigator installed user base will wither away quickly, then I wouldn't have to worry about compatibility problems.
