We love it when hometown companies hit it big! Case in point: Meetup recently raised a big pile of money from Ebay, Allen and Co, the Omidyar Network, Esther Dyson, DFJ, and Senator Bill Bradley. They're apparently using some of this money to buy ads on the subway. Officially the campaign starts on April 1st, but Janelle and Esther both spotted ads today. The spots feature pictures from various Meetup groups-- so there's a chance that you might even be in one. Fun stuff.
