 Well, how about this? Nerds are uniting at the seventh annual BlurredCon convention in Arlington. If you're asking what a Blurred is, it's a community of black nerds. WTOP's Cheyenne Corrine has details as well as a look at some other fun things going on this weekend. The community is very, very welcoming. And this is not just a nerd space. It's also a black space.
