Mark Cuban had some comments on the Free/ Freemium business model…

Lets look at the rule that eventually KILLS all freemium based content plays:

There will always be a company that replaces you. At some point your BlackSwan competitor will appear and they will kick your ass. Their product will be better or more interesting or just better marketed than yours, and it also will be free. They will be Facebook to your Myspace, or Myspace to your Friendster or Google to your Yahoo. You get the point. Someone out there with a better idea will raise a bunch of money, give it away for free, build scale and charge less to reach the audience. Or will be differentiated enough, and important enough to the audience to maybe even charge more. Who knows. But they will kick your ass and you will be in trouble.
