Here is a brilliant article by Michael Bierut on different reasons why we choose certain typefaces. I personally only use a handful of typefaces for my work, Helvetica, Avant Garde, Gravur, Futura and Univers. Sometimes I’ll throw in other typefaces or if a specific client or project requires a specific one I’ll change it up, but for the most part these are my main guys.        

Typodermic releases a sweet san-serif called Domyouji. I dig it. I especially like the W and K. I actually designed a K just like that for a typeface I’m working on. Weird.

Domyouji was designed as a high-tech body copy companion to Korataki. With a nod to Handel Gothic, Domyouji brings the square-sans into the 21st Century.
       

Great article over at Font Shop about other sans serif fonts that have a similiar feel as Helvetica.
