I don't understand your hesitation to share your photos (or at least, not based on that criteria). "[wouldn't] be welcome"? By whom? Facebook? Or your friends? Would that imply they'd rather see ads and shared crap content than original content?

IMO Facebook needs an "original content only" setting. I block every single page that some idiot shares, but I'm not sure how much it helps. I will literally never want to see something shared from another page.

It seems like this would be a good thing for FB too. Keep engagement up, keep inserting ads. Hell, they could insert MORE ads if the content I saw from my friends had a greater signal:noise ratio.

Anyway, I recently shared some vacation pictures and quite enjoyed it. So much better than a bullshit "story" that lasts 24h and nobody can engage with except via DM. Such a weird impulse for an app. (okay, I get that they want you to use it constantly so you have FOMO about missing content that disappears after 24h, but I don't get why they don't want any real user engagement on the content).
