congruency

My rule about identifying yourself by at least your first name has come under criticism by a poster who uses both first and last name.  The critique: 

You may know who “Jeff”, “Steve”, “Mathias”, and “Patrick” are, but how is anybody else who visits here supposed to know?  Do we have to ask you for their identity?  That’s really no different than the rules over at Olyblog, where the moderators seemed know most of the real names behind the screen names but none of the rest of us did.

That’s a very good argument, so good that I have to agree with it.  It’s not fair for me to be the only user who knows everybody by their full name.  Henceforth, I’m changing the rule.  Full names, first and last, are required to post here.  My site.  My rules.  People here will know who wrote what they’re reading.  Maybe this will never take off.  But, I defeat the whole point by compromising on full identitty.
