It’s like a snake eating its own tail:

https://m.facebook.com/ClydesOnMain?refsrc=https%3A%2F%2Fwww.facebook.com%2FClydesOnMain#!/ClydesOnMain?refsrc=https%3A%2F%2Fwww.facebook.com%2FClydesOnMain

Wonder what’s going on? Well, Facebook’s mobile site (m.facebook.com/ClydesOnMain) is tracking the URL (using the refsrc GET parameter) I came from (www.facebook.com/ClydesOnMain#!/ClydesOnMain)—a single page “web app”, hence the hash-bang: #!—that was tracking the original referral page (www.facebook.com/ClydesOnMain).

I hope they got all that.
