For everyone asking, I tell you what. I'll write something long form here soon. That post is probably 20 years overdue anyway.
But let me give you the preview: If you want 1 or 100 or 0 names, personas, identities, alts, whatever, that's awesome. Don't let anyone tell you that there's only one you, or a concept of a "real name" or a "true identity". You define who you are at the moment.
