"logged-in only" editing

It would be wonderful if someone were willing to do an experiment on disallowing some forms of anonymous editing. I'm glad to see that Russian Wikipedia is at least putting it to vote. (Have others considered that as well?)

Strategy wiki is, in its own right, a project, and we could certainly consider running an experiment like this. If we were to do this, what metrics should we track? And what metrics could we point to now that would argue for disallowing certain forms of anonymous editing?

The conclusion to the discussion in Russian Wikipedia was drawn yesterday - to keep the option of anonymous article creation.

Here, on one hand, I do not see any point in allowing anonymous editing, on the other hand, a number of anonymous comments have been added to the treads, which means some users have chosen not to register for whatever reason.
