@Joshua: It's more of a low-priority thing, though the reasoning is that integrating multiple different products for one site (blog, wiki & forum) is very painful and there are sites that use all three: http://smspower.org & http://sonicretro.org for example. Though to be honest, I would never want to match their features, a Camen Design wiki would have to be fundamentally different than existing wiki software.
“Can we have atom feeds with paging and archive support?”
Yes, that would be a bear-minimum requirement for any new NNF. (I'd also want it for multiple-attachment support)
