That's a great point-- one of the recurring themes we hear from speakers at YC is "you can't underestimate the importance of distribution". That being said, I'm always a fan of nailing the most important distribution tool there is-- word of mouth-- before focusing too much on anything else. If you can't tell 10 people about it and have them be excited enough about your product to tell a few more, then distribution is really just pouring water into a leaky bucket. Facebook apps are a fine example of distribution-mania that ventures into the realm of unhealthy. Turns out, no one really wants a lot of those apps-- so their active userbases are dramatically declining.
