I'm a "blunderer" ... (I'm incessant)

Yeah, uh, remember that post about my mistakes being fundamental ... blah, blah, blah ... well, uh, can someone please tell me when I am actually going to start learning from them? Yes, yes, that would be useful information.

(Oh, and yes, I can make "blunderer" (you know, blunder + -er) a noun if I choose to do so.)
