What The Hell Does Mark Cuban Know Anyway

So I see Mark Cuban has chimed in with his 2 cents on the Google/Youtube Deal. Has this guy done anything ever that actually made money ? Ohhh ya he sold a domain name to Yahoo. (broadcast.com) Which from what I have read he fell into that deal (although reaping tons of cash from it). Hrmm the benefactor... flop.. hdnet... flopping... any others I missed ? I know the Dallas Mavericks are doing well but cmon I dont think its possible to actaully LOSE money on a pro sports francise. If you read his post today you can see he just kind of recycles what everyone else is saying yet people are hanging on his every word... I love and root for Mark Cuban as a NBA Owner but as a technical person especially when it comes to business I am not that impressed.
