The title is rendered to a canvas element. Doesn't detect retina display, so that's a pity.

Anyone know what the benefit of rendering text to canvas is? Is it done server-side to protect the font info?

That's Cufon -- poor man's web fonts. Cufon uses flash to show text with the font you wanted instead of loading a font file, which wasn't possible until CSS3.

It now uses canvas element instead of Flash, AFAIK. Maybe it falls back to Flash when the browser doesn't support HTML5.

A bit OT but: Shouldn't it better to use native CSS3 font feature instead of canvas? Guess I know what I'll research this evening.

web fonts were available in the late 90s... long before css3
