I would like to use the name Matthias on the internet, and since Matthias is fairly uncommon, you'd think I could get away with it.
Probably the most well known "Matthias" is a YouTuber. His popularity is the biggest thing that makes me hesitate when committing to using "Matthias" as a name on the internet. Ironically, his birth name is Matthew, and he goes by "Matthias" because "Matthew" is too common. Imposter Matthias stealing the uniqueness of my birth name!
