DASH GPS and Jason Calacanis

Another social networking contest, this time this is not an entry in the contest. Jason Calacanis posts about a contest on his twitter feed, and swarms of people show up and enter. Is this an abuse of these social networking tools? If so, how? It feels like an abuse to me. But I only added him to my followed on Twitter because of his MacBook Air contest. I have no good ethical reason to say this is an abuse of the concept, but it feels like it was.
