Cheers pg. The reason I asked was because when my cofounder and I submitted our application for w2011, we decided to use his account as the lead even though I had way more karma, which was due to him having a much cooler answer to the non-computer hack question specifically addressed at only the lead.

Anyway, not that it matters since a good application is still a good one (and vice versa), but it's possible to find a higher YC/HN participation rate if you include the cofounders.
