This should be a great time. As a non-programmer, I rely way too much on my CMS to do things for me, so I'm always looking for the best platform that I should be on.
Funny, when we first started thinking about this, it was to have a look at web frameworks (Django, Rails, ASP.NET, etc.). It quickly shifted to publishing platforms when seeing the discussion around re-doing pdxwi.com. Sounds like a web framework topic might be something to keep on the agenda.
