Ask HN: Internet got boring, help me?

I feel like I'm in a content bubble I made myself - by disregarding lots of sources with low quality or high quantity - and it feels as if I read everything there is interesting online - which obviously is not true. So to broaden my horizons, please tell me: What are your most interesting places on the Internet, the ones you check daily or hourly? And I mean actual places, like specific blogs, subreddits, groups or lists - and not Facebook or Twitter in general.

Mine:

HackerNews - obviously

The Verge - duh!

CAR Mag UK - http://www.carmagazine.co.uk - showing top 4 news a day is enough, I like that it's not overwhelming with content

Clients from Hell - http://clientsfromhell.net - I even get push notifications via Boxcar, looks like I'm addicted

Priceonomics - http://priceonomics.com - their blog articles blow your mind, but they post a bit too much, so I read ~10% of the lot

As you see, I'm not asking about a specific topic, but what drives your daily content - in general. I'm also looking for tweeps who share articles worth reading like I try to: https://twitter.com/f055

Thanks HN!
