Right, first I noticed Twitter doing it and then YouTube. I thought, someone sold those corporations new tracking tool or an existing one got a new feature.

But Twitter doesn’t appear to do it anymore.

Maybe it's just buried in a POST somewhere and no longer a urlparam?

That would defeat the whole purpose of the parameter for tracking links shared off-site.

Thanks for the correction.
