I'll share a few I like:

Urbansketchers.org (my love for art combined with my love for urban design)


The Atlantic (I wish I knew of more news sources that really focused on useful news instead of sensationalist news, so far The Atlantic is one of the more decent attempts at this)


Oldurbanist.blogspot.com (all about traditional urbanism)


Ambrosia For Heads (I used to have this on my old Feedly account, now I can't seem to add it, but definitely one of the more respectable hip-hop feeds out there)
