I had the pleasure of spending yesterday at YCombinator’s Demo Day. 36 companies presented and launched – three of which were Dogpatch Labs residents: Fanvibe, Rapportive, and an off-the-record company.

While there was plenty of news around the companies, spaces, etc – I found it interesting to see how the crowd of YCombinator entrepreneurs, investors and friends / family checked into the event.

The result? Totally even: while the numbers fluctuated a little bit, there were roughly 15 check-ins on Facebook Places and 15 on Foursquare.
