The handy thing about names of all sorts (includiong pseudonymns, nicknames and handles) is that if someone says something interesting, you can click and find if they've said something else interesting that you'd missed. Or if you think someone is contradicting themselves you can check up on them - that's a bit sneaky.

Anonymity proper - ie posting as GUEST doesn't allow us that, And there are times when there's a fair enough reason why that, like this thread. But it gets annoying when it gets confusing to tell whether two unadorned GUESTS on the same thread are the same person or not. Partly that is because you tend to know that they are just trying to be annoying. And if you want to annoy people there are so much mmore interesting ways of doing it.
