Re: Who'd be a web designer?
@Ken Hagan: If only this were about typefaces I'd ask you outside because the right typeface can be important. That said, I'm not a huge fan of web fonts because they do tend to be pretty big and block rendering.
However, if it's about icon fonts then hahaha. Icon fonts were always a stupid idea because they break accessibility by repurposing code points to display graphics with no semantic equivalent. SVG icons are a much better fit for the requirement and are non-blocking. But I reckon it'll take a couple of years for the web monkeys to catch on, especially as none of them will bother testing for customers with IE.
