Pretty obvious he had to go. Was in the position too long, and his "vision" became damaging. BOD took a long time to pull that trigger.
It is interesting that it is taking so long to find someone who will take the CEO job now that 95% of the "buy-able" competition has been bought, the new products are still poorly integrated and the primary product line is stale (5 or 6 years on RE).
... how long before SalesForce steps in ... ?
Tough job for the new person ... and most of the upper upper management team is new (especially to fundraising) ... we'll see.
