I think the argument of what browser(s) you do/don't support really depend upon your site's focus.
I'm pretty sure if Gruber/daringfireball.net dropped all IE support, his traffic decline would be close to 0.
On the other hand, if codeguru.com did the same, their traffic would probably drop off close to 75+%.
If your budget is tight or skills limited, focus on your target market first and make that experience the best you can. Though, that pretty much applies for browser support as well as many other things.
Absolutely. I work for a 'start-up' in the insurance sector, where everyone uses IE (the only non-IE entries in the access logs are myself on the development sites). If we ignored IE (and I'd love to, given the number of headaches over the years) we wouldn't have any customers.
We could get away with not supporting Chrome and Firefox though as I doubt anyone would notice.
