I don't know generally the use case for this though I remember seeing the most brilliant person I've ever encountered (a forum long ago) enquiring if a job enabled people to work anonymously; he was very cautious with his identity.

I do think it makes sense in this day and age - with pseudonymous discourse long established online - for people to be able to work anonymously within reason (constrained by accountability and transparency when applicable).

The site is interesting but perhaps a little gung-ho with some of its statements.
