What I really want is a kind of system where I can share an article with my friends, but they shouldn't be able to see any of my other articles or "profile" me by viewing all the other articles published on my profile.

This is by far the biggest hindrace to sharing well meaning articles with friends and family. I want them to read one thing, why should they be able to see and read everything else?

A link where they can only view the article I've shared with no other navigation options on the page would be a priceless feature to have.
