I strongly disagree. If 1 single browser out of 8-9 in common use doesn't support web standards, and represents a fraction of a percent of my target audience, then I'm not going to spend time crafting workarounds to target that browser. I already make compact web sites compared to my peers -- no jQuery, optimized images, mostly text-driven. No JS is required to navigate and view the site. A hair over 100 kb for most of sites, including blog and header image. I use global CDNs. So my sites are friendly to users in developing countries, as long as they don't use Opera Mini. There's nothing "bleeding edge" about supporting JS and CSS that IE8 supports. That's as low as I'm going, and no guilt about it. By the way, have you actually tested any of your sites on Opera Mini? You may be surprised at just how poorly it renders, unless you're still working with tables.
