At what percentage of total users can you stop worrying about an older browser? I was looking at W3C's browser statistics, which is a great tool, and was thinking about this. I am sure anyone who has done any kind of web design or development knows which one I am talking about (for those who haven't, I am talking about IE6, IE6, and IE6). IE6 is now down under 9% of market share, yet staying compatible with it causes huge headaches and bloated development work loads.
Of course your market comes into play. Gamers tend to be more updated with current technology, so I would likely have no issue with cutting IE6 out of the picture with a PBBG (and some of the complex AJAX basically demands it). But what about more general public sites as well, who more closely resemble the statistics of of W3C's data?
Anyone have any thoughts on this (both on game-related sites and others, if you have thoughts on both)?
