I love writing under a pseudonym - though my scriptwriting/screenwriting is done under my own name, I feel like I might change that. Writing on Medium is different and my psudeonym is more of a point that I don't want to be pre-judged, people make all sorts of assumptions about a writer based on their name, their profile picture and their bio. I want to give people as little to go on as possible so they're forced to read my work properly. Pseudonym use is great - and i think should be used all the time for judging contests etc.
