Out of curiousity, why did you submit your pitch if you knew it was so-so ? - aren't you worried it might damage your reputation (first impression, etc.) if you want to approach KP in the future for funding ?
I'm not worried it would damage my reputation. 9 out of 10 ideas are poor ideas to begin with but some evolve into good or great ideas eventually. Even the ones that get funded don't have great ideas, the best company they have funded is ng:moco. That company is just an iPhone game company. Not exactly an original idea.
