I again was listening to the Grand Central Gang from the Gillmor gang. My only comment on the whole podcast is simply the choice in changing software platforms is not solely based on the technology. In my experience significant change in corporate technology ecosystems is heavily influenced by its IRR and if it is significantly greater than the IRR of current solution. There are many innovative technologies that get adopted slowly because no one is able to produce a cash flow analysis that can move the company into action.
As geeks we sometimes see the potential in technology but the realization of that potential usually trails significantly. This is due in some part to the inability of us geeky folk to relate the technology to the business. In addition to our geekyness corporations (read large) like to have projects that have high batting averages (read no failures). Even more limiting is the corporate desire for not only high batting averages but high power numbers (read no failures and big returns). Short term thinking of many middle managers adds to the ideas of no failures and big returns.
This is why we see time and time again small upstarts using technology to redefine a market and beat established companies.
