Seconded. It took me several years to go from Anonymous Monk to Anonyrnous Monk :) — and that was primarily motivated by minor benefits like custom CSS, being able to update your nodes, etc.
In case you wonder why... it's that I think that in places like PM, what is being said generally is (or ought to be) more important than who says it. Of course, there are also instances when you'd want to have some "authority" info - in the sense that what a PM Pope or other long term member says is more likely to be correct than what someone without a traceable history says (in particular if truth is hard to verify independently) - but those instances are rather rare, IMHO.
(Actually, I once had an account here, but I switched back to posting anonymously, because I'm susceptible to such silly games, and as a result I found myself spending more time here than what is good for me. In the hopes of having matured a little in the meantime, I gave it another try... ;)
