If you have a good reason to use a nym (you’re a whistleblower, e.g.) great, but otherwise, I don’t see what it does except imply you don’t want to be connected to what you’re saying IRL. 

And I don’t really see how nyms create more community than real identities, or erase status. There are famous nyms and not famous ones, ones with lots of followers and few. 

And you definitely don’t *need* to do this, but I’m suggesting one should because the things people are saying (most of them at least) are perfectly fine to have connected to your identity, and we should normalize that being okay rather than being terrified the State will get us or some future employer will not hire us on account of it. It just makes that state of affairs more and more real IMO.
