These are good points ryanelkins, especially about the distinction between "having wide appeal" and having customers that know other customers in the market. This was definitely a problem we faced early on. Essentially we thought we'd be selling to students and instead we've done most of our business with non-students. Regarding the rewards, we did offer both the customer and the person being referred free time on the site as a reward, but either we didn't do a good job making that clear (very possible) or it wasn't compelling enough. To be honest, we're still not sure which it was.
