CNBC asked billionaire dotcom entrepreneur Mark Cuban, owner of the NBA's Dallas Mavericks and author of his own blog, to comment on the revelation that Whole Foods CEO John Mackay had anonymously posted comments about his company and its arch-rival on a Yahoo message board.  This is how he responded:

I haven't read a ton, just a few articles on the subject. But I can tell you that I feel bad for Mackey. When you eat, sleep and breathe a company, it's hard to disconnect from all the emotions involved. When I was President of Broadcast.com (in pre-FD 1998,9), I used to post as myself on Yahoo message boards all the time. Why? Because it was a great outlet to discuss the company. Some guys want to argue Bonds vs. Aaron, but it's more fun for an entrepreneur to discuss WFMI vs. the critics.
