Additional details - I actually made several comments that all showed my reputation as 11 (sorry, I probably should have screen-shotted them all) without that changing my reputation. My guess is that reputation recalculates every time you up-vote (which you do every time you blog unless you uncheck the box). If the re-calculation occurs before the up-vote (which I have to suspect that it does), this glitch is a harmless one (except for probably confusing people -- like me ;-p ) that just indicates that the user has never up-voted (or, presumably, flagged).
