Amplify

I see a lot of people using this, and sometimes it seems interesting.  I'm going to give it a try tomorrow, but my only concern is of the content.  Most of what I see people posting to twitter from amplify or something similar, is all the same stories rehashed by a ton of people.  That isn't really social networking, the first time someone posted it yes, but after that it slowly becomes nothing more than spam.
