Ranging from friends, to famous developers, to blogs I recently learned about.

Hope you check these out and follow them.
Not all of these have an RSS feed (or their own website at all), but some do.

• Derek Yu

  Probably needs no introduction for some, but he's the creator of Spelunky! In addition to these posts, he also wrote a book which I really recommend.

• Joelchrono

  A friend of mine and the person who introduced me to Jekyll. Writes about tech, games, and a lot of other stuff.

• Kev Quirk

  Only been following this guy for a little bit, but he writes about a bunch of stuff. From tech, through blogging, to life.

• Rach Smith

  Similar to Kev, she writes about a bunch of different stuff.

• Roman Hyacinths (Jaylus)

  An artist and gamedev who's started a blog of her own!

• sirmilkman
