Yeah it seems that YC made the right choice by not letting them in. I can imagine YC being a little picky about what press they would allow into Demo Day because they only want positive news about their start-ups...and who can blame them? I don't have anything against Pando, but I've never heard of them until now, yet I've been familiar with TechCrunch for a long time. YC is comfortable with them and this is there event, therefore, they have the final say in who can attend...even if it only is TechCrunch.
