Firefox not Sustainable?
This article explains why Firefox cannot continue to expand at the rate that it is, I see why this could be true. But I really am excited by the way that people have seen it's a better tool and actually bothered to switch, some of them are people not normally bothered by this type of thing (luddites). I say keep going, keep trying to get people to try it and maybe it'll stick around in the numbers that it's being downloaded in. Try Thunderbird too, i'm using it for RSS feeds and my G-Mail account and im pleased with it so far.
