Adina Levin pinged my last entry on the conceptual well formed log entry discussion and said Tim Appnell [sic] is somewhat concerned about the use of the wiki; because people can edit the pages, he's worried that people will go into loops, changing the meaning of content.
That isn't exactly what I meant. What I meant to say (and did rather poorly I suppose) is that a wiki does not sufficiently facilitate discussion over time or communicate reason for the change nor does it alert me to the change which may change the context of the collaboration elsewhere. I have to really dig for it. (Perhaps this is just my experience with MoinMoin the wiki Sam Ruby is using.)
I think Adina comments are right on as to the different modes in a decision cycle. Wikis have their place, but they are greatly enhanced when used in conjunction with comments boards/mailing lists and a weblog. Going forward I believe that there will be closer ties made between the three. This excercise is both proof and insight into the current shortcomings and potential of this space.
