That's because I spent $30 on advertising. ._.
Though, I have to say, 65 likes for $30 is not bad. Not bad at all. That means that probably for $200, I could get together 400 likes. Having half a thousand likes means something. In comparison when I spent $30 on Jango (an Internet radio site), I only got 5-6 people who liked my music. Facebook advertising seems to be much more efficient. Plus I can keep people posted easily by just posting a new status.
