original post link

An  original post link  (or original post permalink / OPP ) is a hyperlink from a POSSE copy to its original indieweb post.

Why
You should post original post links on a POSSE copy of your original post in order to make it:
 * more clear that the POSSE copy is a copy
 * easier for humans to click through to the original post
 * enable original-post-discovery for readers and other uses like preferring to link to and display original comments instead of their POSSE copies.

How to
When you post a POSSE copy, you should link to it at or near the end of the content of your POSSE copy with text like:

"(Originally posted at : URL)" "This was originally posted on my own site."

For shorter POSSE destinations like Twitter and Foursquare, consider using a simple trailing permashortlink.

Ideally you original post links should use  as well.
