Sometimes I repost funny memes I see here. I like to give credit for the source when I repost, especially as I get so many comments about how good the stuff I'm reposting is.
If people have chosen to have a PLP enabled, I can link to the original post, though I have to screen shot it for it to be visible in FB.
It would be a way for people to see what's going on here, since they can't actually view discussions here without registering.
