And how it's not secret. Or more specifically, things you post on the internet are not secret. Your blog is not secret. So if you decided to not tell a bunch of people, for example, that you were unfamiliar with the piece of music you are conducting but have decided that it doesn't matter because this world famous opera isn't that hard, well, perhaps the internet is not the place to post it. Assuming you wanted to continue to hold on to this secret. If instead you wished to be pummeled by critics noting that it was clear you did not know the piece well enough to conduct it, well, then job well done.
