Tiny nitpick: instead of using the nested circle diagram, I feel like a venn diagram would be more accurate. I don't think that all developers are blog readers.
Yeah, that's true. I considered a Venn diagram, but I feel like those convey that the emphasis is on the overlap, whereas I actually just want concentric circles.
I think the issue is more the top-level category. I should change it to something that strictly contains "Programmers."
