How do you propose Disqus earn revenue/stay in business. There's little incentive for publishes to pay for a commenting platform when they could just go back to using a shitty internal solution. (Although, admittedly, some publishers do pay discuss for enterprise solutions, but if that were more lucrative than ads, why would the bother with ads?) I never cease to be amazed by people who bitch about seeing ads within a product/service they use for free. Someone has to pay for this.
