Montserrat—Montserrat is a libre sans typeface designed by Julieta Ulanovsky in 2011. It was inspired by the typefaces found on older signs in the Montserrat neighborhood of Buenos Aires. Montserrat's creation was funded through Kickstarter, where one can learn more about Montserrat's beginnings. Montserrat is available for free under the SIL Open Font License.
FF Tisa — It's a nice looking font and it looks good on a Retina display.
A Note Regarding Monetization
As of February 2013 I have joined Amazon's Associates program. The Associate's program enables me to link to products on Amazon and earn a percentage kickback if you place an order. I don't expect to get rich here, but I'd be happy if I earned enough to pay for the costs of this site. If you'd like to, you may shop at Amazon and support this site.
