Hi David,
What kind of features you are planning to go into lars-blogger development?
I am very interested in blog features for knowledge management within corporations. There is a yahoo group on this discussion here http://groups.yahoo.com/group/klogs/ (i think this group is not so active nowadays) and Bill Ives blog on Portals and KM has lot of reflections on it here http://billives.typepad.com/portals_and_km/
In the OpenACS community i know
Dave Bauer and
Michael Feldstein has a lot of tips on blog development.
Nick Carrol have been work in dotFOLIO and
Jeff Davis works in CoP software; both of them includes weblogger as important application.
Most of this developments are going on oacs-5-2 branch so i think you could see if your interests on developing lars-blogger could match in these projects.
