Now you know

When I’m working on something and get an idea for a visualization, when I’m following the news and realize I have something empirical and timely to offer, when I want to make a pedagogical point about data or methods or demography and inequality — this is when I generate Now You Know tweets (or, now, Mastodon toots). Sometimes they resonate and are popular, sometimes they are nichey or just fall flat. But the great thing about social media is I get to find out what works and what doesn’t, for whom and why — quickly. It’s great feedback about both the substantive work I do and the method and media of presentation.

I put some of the popular or interesting ones on this page. You can follow the links to see the original tweets/toots, replies and comments, and in some cases links to data and code.
