This is a post from 2014 that I thinks is as relevant now as it ever was.
I like it’s thesis, that even without looking for anonymity, we might want to live in a world where we can inhabit more than one identity.
A persistent pseudonym establishes a local identity: You always use it on a certain site or sites, and you build up a history and reputation under that name. You might use one pseudonym to write all sorts of product and service reviews, another in a support group for a personal health issue, and use your real name in discussions on professional forums and to comment on news stories.
I think this is a fairly reasonable position to adopt. I also think it should be achievable to have a system like this.
At the end there is a suggestion that camera’s and facial recognition software means we will loose of pseudonymity in the physical world and so we might need to find it in the digital world. I’m not sure I agree with this yet.
