My opinion actually leans more towards No then Yes, but since I'm unable to justify it even to myself, I have chosen "no opinion".

For some reason, I have the weird feeling that people who disparage PE are subconsciously voicing their dislike towards ShadowRabbit rather than the lack of productivity from PE. I mean, there is no denying that PE has not done anything useful (yet) and may never. But if people are willing to give it a (second) chance, and probably even contribute to PE, it may very well turn out useful. Unlike listserver admins, PE has the specific goal of reporting hackers/crashers, so first-time crash victims will feel more comfortable reporting to PE rather than a higher authority. You could probably take PE one step further and add in a security programmer or two, and make some anti-crash programs. Sure, Jazz2 will never become a utopia, but PE is, as far as I know, the only effort that has been started with the objective of bringing that goal closer.

On the other hand, this does not mean that I don't find PE unproductive. I just think that nothing too signficant has happened yet to gauge whether PE is useless or not.
