If someone else asks himself why you’d want a font icon instead of an image, I found an explanatory page: http://css-tricks.com/examples/IconFont/

It's still a hack. It's time to go with SVG instead.

Here's a good writeup of reasons to stop using silly icon fonts and start using SVG.

Does IE support SVG already?

[freshyill]

I've had a lot of success using SVGeezy for image replacement and Modernizr to help with background images.

I don't really see how this is better than <img src=".." alt="You won't find me on Facebook" />

Have you ever tried adding images for use as icons that look good on retina or HiDPI displays? I use icons for their perfect resolution at every size, no matter your pixel density :)

This seems to make things visual only, with no alternative text for others.
