For those of you flying to Cambridge (we didn't make it) and those who did not but have an application that they need practice demoing and would like feedback, I propose having 2 practice demo runs prior to the YC deadline. The first one to find the glaring problems, and the second to polish the presentation. We are going to demo for other investors, so we need the practice too. We have an office right across from Cnet.com with a large conference room perfect for demoing. Let me know if you're interested.
