I was just doing some Google searches to find out how to selectively always trust certain certificates on intranet pages using Google Chrome on a Mac. I came across this SuperUser answer. Another link in the Google Search pointed to this comanswer page, which exactly duplicates the superuser.com content!
Anyway, just wanted to call this to attention & I don't really have a specific question (apologies & please close this if it's inappropriate for meta.su).
Same thing happened with a question that I submitted to Super User (duplicated as a YouTube video with attribution, and an actor reading it, which was very odd). I guess it's a way to generate free content.
