Veering on topic for a moment. R=U gets a lot more stick than it deserves in my opinion. I can't remember the arguments fully, but I defended an agnostic position regarding it back before Ultimania got brought to light. Now that Ultimania is around the whole thing does seem a lot less likely, but don't let people tell you it was just a crazy theory by stupid people. I have been in countless numbers of these debates. There was plenty of evidence to at least suggest the possibility of R=U, and many opponents of R=U often presented far less reasonable arguments and (thanks I guess to their side being more popular) did so far more arrogantly.
