Unfortunately I find popups that jump in your face not compelling. Even more when they track that you are reading the page to make sure that they are in your face... and all of the developers I know also feel the same (I haven't asked to non-developers)<p>However, the heading seemed good enough, it clearly stated that it was a card game. If the reader doesn't participate in the discussion, how do everyone know what he's thinking or what he's going to decide?
