I clicked, read the webpage, went back to HN for an explanation in the comments. Unfortunately there just other human beings as confused as I am.

So I googled it and found this: “decentralized autonomous organizations” (DAOs) https://blog.ethereum.org/2014/05/06/daos-dacs-das-and-more-...

The way I understand it, it is for building an organization that is somehow "autonomous" and decentralized. I put the autonomous in quotes because I am still not sure what that means, though I understand the decentralized part.

Two other descriptions, from slightly skeptical observers, were: Decentralized Corporation Decentralized Venture Capital
