I enjoy Thoughtbot's blog. Though I honestly get more of my news through mailing lists related to Ruby and Docker - I don't really subscribe to blogs anymore. There's too much to follow, I prefer getting some of the "best" sent to me. I need to add some JavaScript lists, and possibly some stuff on design.
I love my Tweetdeck with Twitter streams from nuclear (one account) and data science (one other account) top players and influencers. More interesting and focussed than blogs.
