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!
