I think there's a particular danger here
Using a real-world person's name as the handle suggests that they themselves are posting here.
That is misleading, imho. Certainly, on the Space Board it would get you busted instantly.
I'd prefer if this did NOT become seen as "accepted" behaviour.
I am, and always have been, in favour of fixed handles, and registration for using this site. That covers SO many of our issues about malicious posting...
