Warren Buffet / Berkshire Hathaway is WAY behind on their taxes... See:

Warren Buffet despite his foibles as we know is a crazy good investor. The question in my mind is why invest in newspapers when there is some evidence that they are a dying business model. On one hand, there is always going to be a need for news (and writers / journalists) but a much more decentralized model seems to rule day as many of the blogs do (such as Huffington Post). I would be really interested in knowing what his game play is as far as the newspapers are concerned. It could be they simply allow him to play in the political arena at a higher level than before.
I'm not a fan of Warren Buffet at all as he despite his carefully nurtured "grandfather" demeanor plays real hardball and screws people left and right. (The lady who used to own Business Wire got screws IMHO as she just sold it to him cheap simply because she liked his "grandfatherness.") In addition, he is well known for advocating higher taxes on the "wealthy" on one hand and not paying his taxes on the other. As many say: "Watch what Warren Buffet does -- not what he says."
