Having said that, I suppose plenty of #Scifaiku is the same as my #SFHaikuesque, referenced via a different name. In other words, I think a lot of it likely is a #Haiku derivative, discernible from haiku, and which treats science-fictional topics, without the science-fictional aspect being an extra aesthetic layer — not that doing so is wrong; it's simply not what I do. And as I also write #PhilosophicalHaikuesque, I use the same word because it likewise is neither haiku nor senryū.
