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.
On that note, do you mind sharing the list of podcasts you subscribe to?
