Ask HN: Where do YOU go to learn about blockchain?

Where do you go to get informed about Blockchain? We're researchers looking at blockchain applications, and want to have an overview on how people read and learn about the topic.

One half of our research is purely academical publications, but the other is the real world. It would be super nice if you could do a quick comment of where you go to learn mostly about any Blockchains you're interested in.
