Lots of good stuff in there. The Neil deGrasse Tyson complaint is a little frustrating... science education is important and there's something to be said for getting a lot of people to have a broad respect for science even if they don't do it. I'd be happy if a lot of non-economists knew they didn't do economics but maintained a healthy respect for what an economist says about the economy relative to what some journalist says. Still, a lot of good points here.
I don't follow the page actually, but I think a lot of it is funny/pretty/etc. But that's the whole point. Don't like a page that's funny and make the mistake of thinking it's more than that that you're viewing and "liking". Like the joke or the inspirational picture, but know that it's a joke or an inspirational picture and that science isn't done in one-liners with a pretty graphic.
Here's an assertion that I think is largely true but that is sure to piss a lot of people off: John Papola is the internet's "I fucking love science" page for economics. Flashy and visually impressive. Funny. Gets people excited. Piques the interest of people who are genuinely into economic science. But really botches a lot of stuff and smuggles in politics.
Discuss, but know that this is my space and I'll heavily moderate if it needs to happen.
