this seems weird to me - you crapped on the guy for telling you to shut it down, but told him 'thanks' in another comment for presumably telling you to to shut it down. seems a little passive-aggressive, but to each their own.
in any case, we prob need a statusbar at the top of every 'check out my new site/app/business' post that says, "Yes, we _know_ there is already one of something like this -- maybe even two! And we're still doing it. We'll call you first, next time, to get your permission."
outside of that, i think commenter's question was how is this new site different? -- i.e. not necessarily, why are you doing this again?
it's ok, i would guess, if it is not, in fact, different at all, but maybe it is - which is what the commenter actually asked.
