In /fonts/ I keep various web fonts that I use on some web pages.

The League of Moveable Type make some great, Open Source typefaces. Here are a couple I use on this site:

League Gothic

Great for when you need a high-impact headline that doesn't take up too much space.

Linden Hill

Adds a great dash of style to long-form text. I particularly love its understated italic. I do wish it had a more exaggerated x-height, though; I tend to find fonts with a larger x-height to be friendlier to read on screens.
