I like going through Quartz's daily newsletter, and picking a couple of interesting links from there to read.

http://www.avclub.com/ for my pop-culture reads

http://www.theonion.com/ because it's seldom not funny

http://www.thefoxisblack.com/ is a favorite art and design blog of mine.

http://www.thisiscolossal.com/ - contemporary art and visual culture

If only it were updated daily: http://thelastpsychiatrist.com/

For news: Quartz (qz.com) and Vox (vox.com) For sports and pop culture: Grantland

foreignpolicy.com - It's probably the most under-appreciated hyper-analytical and typically apolitical site out there, that has tons of fresh/smart content

sports (espnfc.com, reddit /soccer, /nba) news sites (cnn, wsj, etc.) personal development (ted, physcologytoday, etc.)

www.inc.com for my business motivation
