I'll probably look at the source code soon, but I have a couple of questions first:
What version of asp.net are you targeting, and what are your plans for the future? I don't see much on the roadmap past mid 2008 (i.e. now).
Is there a main development push in a particular direction at present?
What kind of rdf:foaf support do you have - static foaf documents, or generated from user profiles? What fields are generated in the foaf data, and is there any privacy control in it?
Do you accept code checkins from anyone, or just from your core team?
What is your policy on code quality tools (Warnings as errors, fxCop, StyleCop) and software engineering techniques such as automated unit testing?
What prerequisites (add-ons and third party software, e.g. packages such as Enterpriise Library, asp.net ajax controls, NUnit) do I need to install first before building the code?
How is your RSS support done - there is interesting RSS and RESTful web service support in WCF 3.5, but given the age of the project, you probably aren't using that.
