As for them leaving out Netscape, I can think of two reasons. The first is that when Mozilla split off last year, there was a real sense of torch-passing. 7.1 seemed like a last-ditch effort to get something out before they were shut down (with the rare distinction of being a high quality last-ditch effort), and it was clear that all the action would be with Mozilla. The second is complexity. At this point they’re plugging four browsers, two of which are based on the same core. Adding Netscape gives you five products, three using the same core, two of them almost identical. It might be worth adding Netscape info to the Mozilla entry, but limiting the list to four keeps the message simpler — and a simpler message is more likely to get through.

Make that three reasons. AOL had said at one point that there would be no more Netscape releases (before they changed their minds). At least with Mozilla, Firefox, Safari and Opera you know someone’s around to fix any security holes that crop up.
