Good summary, Jack. It was an interesting discussion indeed. Specially the topics where we identified that companies nowadays have to rely on outside information because it is not feasible to collect all information upfront (unless you are google :-)). The half-time of knowledge is shrinking (the time it is valid and/or until it is replaced with new knowledge about something). More powerful tools like google, kartoo, etc. are enabling effective ad-hoc knowledge inquiries. Wikipedia is one good example where a lot of people are referring to a free source of knowledge, but are experiencing that it shouldn't be the only source (see recent articles on editing of competitors editing their competitions wikipedia pages).
For free information, it may be necessary to do 'comparison shopping'. Look at multiple sources and identify the common truth. If one is required to get to the highest level of reliable information, one may need to pay for services that use higher level reliable sources.
There is so much more to discuss on this topic.
