It's actually not that rare. My American friends have been playing it all the time on Merge to mix in with their NLHE tourney sched. I was interested in trying out some of them on Stars.
I don't expect it but it was just an idea. It's not important enough for me to get a coach. I am quite happy with my poker earnings as is.
I am glad you are adamant in not seeing a PLO8 tournament video. I personally do not see the harm in it.
