Cuban's advice: declare war on the "aggregator" Web sites that get a free ride on content. These aggregators—sites like Drudge Report, Newser, and countless others—don't create much original material. They mostly just synopsize stuff from mainstream newspapers and magazines, and provide a link to the original.
Think about this for a minute. The aggregators and the old-media guys are competing for the same advertising dollars. But the aggregators compete using content that the old-media guys create and give to them at no cost. This is insane, right? It's like fighting a war and supplying the enemy with guns and bullets.

I hope bookmarklets and blogs remain exempt from this firefight. ;-)
