Blake Ross gives yet another reason to consider Firefox over Internet Explorer:

People ask me, "Well, gee, if IE7 is starting to catch up to Firefox, and if they've got their hand back in development right now, and eventually they might actually catch up to Firefox in terms of features, what's the benefit of using Firefox? Why are you guys still around if you say that your only goal is just to make the Web a better place?"

My answer to that is, how much can you really trust a company that five years ago completely left you abandoned? If they do, in fact, succeed in taking back some of the market share that Firefox has gotten back from them, who's to say that they're not going to disappear again? My issue is not so much at a product level, it's at a company level. How do you trust a company that left everyone out in the cold for five years?
