Your keys also work on the steem blockchain, Steemit, D.Tube, etc.. Your post's are visible there as well.

All the more reason to keep your keys safe and secure. Do NOT lose them.

It's not the key to just one silly little site you stumbled across, this key gives you access to a network of sites on 3 different blockchains. Like three different snakes intertwined with each other and each snake is swallowing a different snakes tail.

It's a powerful thing.
