Yeah, nothing screams good craftsmanship like armchair-quarterbacking someone else's work that clearly works well.

FWIW, it seems to be some sort of encoded state, essentially HATEOS.

Works well?

"Oh you want the URL of your LinkedIn Profile? Don't use the URL in the address bar, silly! Use this other URL we are providing randomly down the page."

I was referring to the URL-scheme of the LinkedIn app in general, not just the profile page - I somehow missed that this subthread was only about the profile page. Yes, I agree they dropped the ball completely on that. Especially tragic as they could fix the 80% case with a front-end one-liner (window.history.replaceState).
