So, I’ll answer as to why I use my real first name. First and foremost, I always have a hard time coming up with something that’s interesting, describes me, and that I think I’d use for a long time. Also, since I do have an externally facing job in academia, my picture, full name, and bio are available elsewhere on the web, so I’m not anywhere close to a fully private individual. On this site, and the other one I use, I’ve posted pictures of myself, so even if I used a fake name, work colleagues could easily recognize me. Ultimately, I’ve come up with a “middle road” of a somewhat anodyne social media presence, but with my actual name, that works for me.
