Hello, when I saw this workflow, I thought of an article in The Economist a few months ago:
Cartoons: Triumph of the nerds
http://www.economist.com/news/christmas-specials/21568586-internet-has-unleashed-burst-cartooning-creativity-triumph-nerds
 
It mentions several of the "modern, nerdy" comic strips already referenced in your workflow.
I thought I would suggest a few more from the article. Here are the names and RSS from their sites:
