I agree with wedrifid in saying:

The material on the wiki (I assumed) was to be summarised from prominent and uncontroversial blog posts that are already referenced to from time to time.

That is, the workflow should not be "idea for wiki page --> write post --> discussion --> write wiki page", but, independently of each other, both "idea for posting --> write post" and "notice something generally accepted on LW without a wiki page --> write wiki page".
