Who should I follow on Twitter?

Hey guys,

I want to start using Twitter as a means of finding good web software content. I'm a big javascripter. Love reading about interesting new frameworks/libraries/tools, opinions on why things are sucky/awesome, or general how to become a better engineer style articles. I mostly use HackerNews and Flipboard for finding content. An example of someone on Twitter that is posting relevant material is David Walsh. Love the stuff he tweets.

So, my question is: who are some great Twitter users for filling my feed with interesting web content?
