That doesn't really answer reynolds' question at all.

How is this better than spending $150k on hiring, for example, 2 engineers for a year? Or 1 engineer and 1 designer? Or 1 customer service person, 1 community manager, and 1 developer? Etc.

Our investors are really happy with us... we are in fact hiring engineers & designers right now as we speak. And this money is accelerating our growth today. Believe me when I tell you that if you can acquire new users for less money than they generate you revenue your investors will be happy to see you invest money this way! Let me know if this answers the question :) Thx, Steli

It is better if NGOs are promoting the service to their existing and potential donors. It is possible that revenue from giving away $150,000 with a buzz brings in more users than 2 engineers can.
