I am again schooled by @personz! I am sure I learn something valuable from you every time you make a post I am able to discover.
I was unaware of the ability of Steemit to selectively serve content from the blockchain, and will consider this more fully. While I immediately see the reason for Steemit to have this ability, I also am immediately struck that this is something that can be used to censor, and have to think about it before I can make informed comment.
At least posts do become part of the blockchain, where they can be discovered, rather than simply be deleted. That's something.
Thanks for always adding to my understanding!
