For those who are confused about all of this hardfork and Testnet business, all you really need to know is that hardforks are a blockchain-specific term for software upgrades. As you probably know, blockchains are impossible to change by design.

That simplifies it. @SteemitBlog

With a Pitchfork, you can make it so that every vote that occurs on the Mainnet is mirrored on the Testnet, but nothing that happens on the Testnet makes its way back to the Mainnet.

That's great @SteemitBlog

Is there any HF20 for dummies article that you would suggest?
