[mirimir]

Yes, that is indeed a limitation. Nobody IRL will ever know that I'm Mirimir. Also, I can't attend physical events as Mirimir, or do anything with audio/video.

I suppose that you could use other personas for totally non-controversial stuff. Indeed, you could have a range of them, and disclose some if you like.

There is the issue of writing style. At this point, Mirimir is my only persona that writes extensively in English. There are a few others that are basically Mirimir's pseudonyms. But my IRL identity doesn't post much in English. For some others, I've translated into other languages, using offline software.
