This is an interesting idea … http://www.exceptioncollection.com/, something that I’ve pondered before...

I’d have to know more about it, in terms of the privacy and security of their data collection… before I could recommend it without any pause, but I would certainly take a look if you are building a widely distributed application (outside of a single company/enterprise), and I would probably try to integrate with the Exception handling/logging block from PAG.
