Mine is not as large as theirs. I will use whatisit or whatisitchallenge. I distictly remember something like writing somewhere, "I hope you don't mind" or "I hope it's ok to use this tag" in one of my earlier comments or contests. But, you are right. I will build an audience. I have other things to do as well which are normal posts - fire it and forget it. But an active comments section will bring up everyone's reputations!
