Ask HN: Besides HN, what are your most visited sites?

[riams]

The information I've been exposed to while using HN has been invaluable. Some say the key to success is surrounding oneself with those smarter than you, and HN is the closest I've come online.

To make sure I'm not missing out on anything, I would like to ask fellow HNers what other sites you frequent. Thanks.

The tabs I have open permanently (pinned in Chrome) are Gmail, Reader and Yammer (internal startup chat).
