I am sympathetic with Jim McGee's objectives here. "It can be difficult to distinguish a back of the envelope calculation from an SEC-ready filing when both are printed in 11-point Arial." Software developers have developed tools for versioning and iteration toward a final outcome, but "I am hard pressed to identify other knowledge workers taking advantage of those tools or practices." The problem is that other fields of endeavour aren't working toward a specif outcome and the process is often not linear or iterative. One might thing of these posts in OLDaily, or the mess I call my blog, to be working papers. But they may collectively lead nowhere until, one day, suddenly they do.
