On the LLNW board, for some while after Limelight's ER, some of the posters suspected Dan of either (1) intentionally hyping LLNW's price up so insiders could dump before ER or (2) unwittingly being used as a conduit for the same purpose.
Given his blog's timing — exactly one week before Limelight's ER — those conjectures seem highly likely, especially when you remember his timing — exactly one week before Akamai's 2008 Q4 ER — when he announced that Apple was using Limelight for some of its content delivery. Dan had been observing that delivery by Limelight since "the fourth quarter of 08" . . . but DID NOT MENTION it until seven days before Akamai's 2008 Q4 ER.
