Ask PG: Who looks at the demo sites listed in the YC application form?

In the next few days, I would like to list prospective features of the site/idea, details about me, etc on the demo url included in the application.

There are some that I would like to list which I would like to keep confidential and would not like potential competitors ( or investors in potential competitors other than PG, Jessica Livingston, Trevor Blackwell and Robert Morris, because I believe you would not pass on the ideas) to know.

Could you tell if you four would be the only ones who would be going through the demo sites and is there a chance that others (advisors, friends, staff, partners, etc) could also have a look at the demo site as part of an informal decsion making process?

(obviously the scope of this question does not include accidental discovery of the hopefully obscure enough demo site by anybody else)

Thanks in advance.
