Reddit reviews Stylepedia: A Guide to Graphic Design Mannerisms, Quirks, and Conceits

Agit Retro style seems tied to the work of Micah Wright (Propaganda Project), I never heard the one without the other mentioned. I think the term comes from the Russian Agitprop.
You can probably read something about it on Amazon's sneak peek of Stylepedia if you don't value your retinas so much (I passed)
edit : I actually know the term is mentioned in the available excerpt but it's too damn hard to read that thin font on the preview.

Trade half of your brain for half of mine? I'm on the other side of the creek from you. Trying to get into development but already established into design. I feel like the main things that would come in handy are

• Color Theory
  
• Typographic Hierarchy / Typography knowledge
  
• Maybe user interface but I know development plays a role in that as well.
  
  Some great sites to check out:
  
  
• Styleboost Great site that shows uniquely designed websites, helpful for inspiration.
  
  
• PSDTUT articles regarding typography/design
  
  
• Smashing Magazine has a lot of great articles regarding design and user interface. I generally read it everyday.
  
  And if you're really getting into graphic design and enjoying it, I suggest some of these books to dive deeper.
  
  
• Graphic Design Referenced
  
  
• An Eye For Color
  
  
• The Elements of Typographic Style
  
  
• For a quick reference regarding different styles or inspirations - Stylepedia
  
  There's a ton more so feel free to ask any questions or if you want any critiques I'd be glad to help. Good Luck!
