I wouldn't presume to characterize either Rob or you Marshall, but I do have the benefit of much prior discussion with you in this newsgroup, and apparently Rob does not have the same benefit. Much of the tone of Rob's communication does seem to be as if it were between a salesman and a prospective client rather than between two colleagues discussing a technical matter on a public newsgroup.

What I do want to take exception to is Rob's characterization of Diffusion of Innovation as relating to a product rather than to an entire technology. That may be true in the book "Crossing the Chasm", but it isn't true in the original concept of DofI. DofI predates "Chasm" by several years. I was first exposed to DofI and the five stages while still working at Digital.

Here's a link to a wikipedia article about the concept.

I believe that Rob's transformation of a technology oriented concept into a product oriented concept is related to Rod particular intended use for his valuable time. I certainly hope that Rob will feel motivated to spend less of his valuable time writing posts to comp.databases.theory, even though the return on investment might be quite high, over the long run.

Then again, in the long run, we are all dead, according to Keynes. Received on Thu Jan 17 2008 - 22:09:05 CET
