I caution my students often about free fonts online: "Just because something's free, that doesn't mean it's good." Recently House Industries released a free font, Slant. I'll keep my mouth shut about this one. House has an exceptional collection of fonts, along with an awesome store full of cool objects, prints, and housewares. I want it all.
So go sign up for their mailing list and you'll get Slant, + an actual printed catalog you can drool over.
