If you find something on Facebook that you want to share, great.
But if the Facebook page links to an article, please do not post the Facebook link here. Post the actual link so we don't end up with "Content is unavailable right now."
Since I have no clue how to do that I usually open the article from FB, copy and paste to a new post on agnostic.com and do not even say I found it on FB.
Too many times I get the "Content is unavailable right now" so I just post the whole article.
Chances are if it's on FB it's not worth reposting anywhere. Typically if I see the little FB link icon I don't even read the post - so if anyone doesn't want me reading thier posts just put a copy of that icon in your post.
