Some people like to visit Mark Cuban's blog for its train-wreck aspects. You know, how he'll promote his show The Benefactor and say how great it is just before it airs to an indifferent public. We like it, weirdly enough, for all the other posts. Like the one about his take on politics and its effects on the business environment. (He took a shot at Senator Orrin Hatch and never mentioned that he once contributed money to Hatch's campaign, but it didn't affect his point, so whatever.) Or the one about how much he loves his new Sidekick II gadget. (Want one!) And especially the one about the future of HDTV, DVDs and the hard drive. It's in posts like these that Cuban shows he deserves at least a bit of the "business genius" label that is constantly attached to him. True, we long for the post where Cuban shows a smidge of humility, but in the meantime we'll settle for the insight and geekdom he offers.
