I use IE6, basically because its the standard..
I have netscape 4 and 6 and opera..
someone called Opera a nerd browser :P You should try lynx, now thats a nerd browser
Coding for all these different browsers is really a problem, i try to test any sites I make in as many browsers as possible.
Im not a fan of netscape, but I must say that the improvement from 6.0 to 6.2 was quite noticeable.. after 6.0 i thought for sure they were doomed, it was big, slow, ugly, crashy, etc, i never used it.. but (Again just for the sake of testing) i upgraded to 6.2 and its pretty good... still has that annoying loading screen, though, which IE doesnt..
