Names are a complicated thing. I have several, myself. I hardly ever use my birth/government name for anything except official documents. At work I’m mononymously known as Red for reasons so old they’re forgotten to all but myself; but it’s not so much a nickname anymore as it is my work persona; I even use it on the phone now. A very limited set of people call me Dad or Daddy. Almost everybody else calls me Kith, and that’s the name I use online. It honestly wouldn’t have occurred to me to use one of my other names here. I don’t normally think of it as a pseudonym, but since it’s not on my legal documents I suppose at least some people would.
