My one question would be: can you be as brutally honest as you need to be on stage with a team you've never seen before and might never see again? If so, then I think this is still an invaluable experience for the companies - most startups that just get feedback from their friends and a few early adopters don't get to hear the things that they need to.
cool, whomever down voted this you are a pretentious ass - rather than explain, you downvote.
As a side thought:
Given that we have had this ongoing discussion about the comment scores being hidden to preserve real dialogue - we should require a comment for every downvote, such that every downvote comes with an explanation or talking point for further discussion.
As it stands, the downvote is a silent and anonymous point of disagreement -- is allowed, and becomes visable (through greyed out comments) -- where the ability to see the comment's upvote count is not allowed and not reflected in the font size/color of the comment and thus invisible.
PG, I respectfully disagree with any and all reasonings you may have of hiding comment upvotes, and my opinion is only reinforced through the visable effect downvotes have on comments.
I worked on this webapp with ez, guz, and others. The idea is that people with knowledge/expertise in a subject can "hold office hours" with (strangers?) people looking for advice.
I also don't know if it's going to work. I compressed the time slots about 3x to make it interesting for the audience. Since I won't know the startups already and the time slots are so short, the result will probably be more like YC interviews than office hours.
