In truth, I don't like the word "scifi" because it is a made-up nonsense word that doesn't even define what I like.
Technically, I would prefer SF and I would pretend it stood for "speculative fiction."
If this is an amazing April Fool's setup and Joaquin Phoenix is involved, you utterly win. I will bow before your greatness despite the fact that I can name three or four incredibly stupid things you've done and I can't actually think of anything profoundly bright other than that you've shown some good reruns of other people's stuff.
If not...you are so stupid that you should have to go on Jerry Springer and explain why you really and truly think that changing your name to Syfy will make you more money or do anything reasonably good for your viewers or your stickiness or anything else that your silly greedy corporate overlords can possibly make sense of.
