I had similar feelings a year ago and wanted to setup a “diet” for my mind; I’d only allow quality information, opinions to enter my mind, not just random stuff.

Firstly, the best way to access/find valuable knowledge is still books. Then, I have Freenode open in background for technical conversations, and also follow some good quality podcasts in non-technical subjects; from history to art.

If I got a question, I either ask in Freenode or ask trustworthy people by e-mail.

No social media. No news websites (except HN).

I’m a lot happier with this set of communication and information channels.
