 This is WTOP News. Facts matter. 853. Nerds are uniting at the 7th annual BlurredCon convention in Arlington. And if you're wondering what a Blurred is, it's a community of black nerds. WTOP's Cheyenne Corrine has details as well as a look at other fun things to do this weekend. The community is very, very welcoming. And this is not just a nerd space, it's also a black space.
