Outwitters 20Q!

That's really pointless. I will just go on to ask "You are anywhere but in the help section?" instead of asking "You are not in the help section."

The whole point of this game is to find the solution through elimination of options. By posing a question you divide the space of possible solutions into two halves - being clever means formulating the question in such a way that you gain a higher insight without getting too many 'No's.
Asking "Are you Pizza?" as the first question is really counter-productive because the answer will most likely be 'No' and the only information you gained is that the solution is not 'pizza'. Asking "Are you not Pizza?" is still pointless, but no longer counter-productive since the answer will most likely be 'Yes' - and if it is 'No', then you would have won. It would however not be practical to go through every possibility and asking a negative question since the universe is bound to end at some point.
