As a developer I either want complete and utter domination by one browser (so I only have to test on that one) or lots of browsers with reasonable market share (making standards compliance crucial). The current situation is almost the worst imaginable. I have to develop for the (mostly) standard compliant browsers like IE8/Firefox/Chrome and then tweak for IE6 and IE7. I believe this is good news because it's insurance against another IE6 coming along.
