This is nice, but that webfont bullet is a weird take. If you're hosting the font yourself and you're using a modern format, fonts don't add a lot of overhead, and if they happen to fail then the browser will take the next item down the stack. It's textbook progressive enhancement. Nothing about adding a webfont properly will prevent Web content from lasting and being maintained for 10 years.

"your focus should be about delivering the content to the user effectively and making the choice of font to be invisible, rather than stroking your design ego" - these aren't the only two options?
