On Friday night, I got into a discussion (argument) with my friend Kelly about fonts, of all things. Apparently she's not a big fan of Helvetica or Times New Roman. I don't really care about TNR - but it does have its place. Helvetica, on the other hand, is pretty and doesn't deserve to be hated.
Anyway, this isn't meant to be a defense of one typeface or another. It did remind me of a really helpful mapping tool called TypeBrewer. A grad student at UW-Madison created this site and it's a great way to get a template for your map typography. It's pretty cool just to play with the sliders too :)
