I know this is a little off track from the pertinent argument, but why abbreviate Netflix? You aren't saving any time in typing out your response and it can only serve to confuse the reader (I also had no clue what Nf meant).
The parent explicitly refers to Netflix, not "nf" or "Nf". You might say it was clear from context, but for at least two people that read the comment it was not at all clear. It's not a big deal, I'm just always curious about everyone abbreviating things.
