Google Alerts just notified me of a complimentary blog from Primatex Consulting, providing some feedback on Drools 5.0, our future direction and the ORF09 Drools bootcamp :
"My first look at Drools
What was clear from the presentations I saw and the discussions is that the Drools team obviously is inspired by some commercial products, but they will usually take it to the next level. As an example I can think of the ILOG JRules support for event reasoning, but in the last couple of years, ILOG has stayed away from pushing that functionality, and they have not made it evolve. It has the potential of being very powerful stuff, but ILOG did nothing about it. Drools did.
