Got to agree with all of the above regarding Facebook v Steem - posted about this back in the past.

I moved from Steemit a while back, and one thing that bugs me is that I'm not aware of a way to post dApp-agnostic links.
I.e. I have lots of old post links that I tend to add for those who might be interested.
So some of my links are...
https://steempeak.com/game/@hockney/the-isle-of-cats-board-game-a-review
But the older ones are...
https://steemit.com/boardgame/@hockney/merchant-of-venus-board-game-review-if-you-ever-played-elite

Maybe (probably) I'm ignorant, but there should be a way to just point to the post and let the dApp handle the rest?

Again, this is an obstacle, if your reader is on a dApp, not a browser.
Facebook and its ilk are easy. Most social media users don't give a damn about privacy, (pitiful) earnings, encountering high quality content or blockchains. They want easy access to their friends...
