I remember years ago reading that Ainge starts his day reading Hoopshype.com to get an idea about what's happening around the league.
I'm not surprised the Celtics would be very careful to protect their brand from infringement, so I'm sure they have some intern assigned to peruse the fan sites regularly for infringements.
I'd be surprised if Ainge took the time to peruse fan sites like this one. I wouldn't be surprised to hear that the owners check them out, just to take the pulse of their fans. I know one of the minority owners, and the next time I see him, I'll ask him.
