Ars, Tech Review, and Wired (birdman hoax aside) are very relevant tech publications that cover trends that everyone who works in technology should be aware of.

Like many people here, I get most tech headlines via Hacker News. Sometimes I use Twitter. I used to be a big Techmeme fan, but I've noticed A) the best stories on TM tend to show up on HN first and B) most other TM content is the commodity Apple/FB/gadget news and blog theater that I am trying to get away from.
