As another example of Font-Awesome in production: I've incorporated Font-Awesome very heavily on my own blog, and it works very well: http://minimaxir.com
And have you seen how ugly it looks with Chrome on Windows 7? Which should be the most popular browser + most popular OS. So I disagree with you and the blog author you should use fonts as icons.
They look ugly with Chrome + if fonts are not supported they don't show anything. At least if the image is missing you see X.
The only reason I linked to my blog because it is directly relevant (discussion is about Font Awesome, and I've done a lot of development with it).
If there was a way to show off Font Awesome without providing a link to a case where I actually used it, I would. (screenshots won't be as effective since I incorporate on:hover effects.)
Of course it wasn't the reason nor was it the only one. Please. We are all adults here, we all want to piggy-back on HN traffic, but - c'mon, your blog is not a notable example of the use of Font Awesome "in production".
I think that "Hey, I did something relevant to this discussion!" is a valid reason to link to something of yours. People do it with coding projects all the time.
