you read correctly when i last talked to jd i specifically asked about karl .. and he's *in jd's words* .. a friend of the family ..
per jd .. none of them have sold .. one share and have no plans to .. for a minimum of 2 years (that included karl and jd and glenn)
jd is a truly accessible ceo and i would strongly suggest if you have any questions you contact him directly .. and if you haven't already .. listen to the CC held (and recorded) back in july ..
