I use pseudonyms, but it's mostly to keep accounts separate for logistical reasons. My accounts associated with gaming and hobbies have different names than my accounts where I talk about politics and news, and so on. I don't really want to mix those spheres of my life. Of course someone could connect the dots, and I avoid anything that could be truly troublesome. But this provides a useful 'soft' barrier.
