We have done a fair amount of customization to our blog towards what we hope is a improved model for team blogging that facilitates better focus on authors and topics. It is a cross between a team blog (multiple authors on the same blog) and a Multi User blog (each author having their own blog, i.e. MU WordPress),
I have reworked the customizations into a single plugin we call the Blog Matrix (mainly because it sounds cool). I think the Matrix plugin would be useful for anybody that wants multiple authors on the same blog, or way to get some MU WordPress-like functions without the complexities of the MU installation.
I have written a post explaining how the Matrix works.
Intro to the Blog Matrix
(you may want to skip down to the demo)
I would love to get opinions about if WordPress users would find this blog model useful and any suggestions for improvement.
Thanks in advance
Note; for right now only review the Matrix plugin functions. We have not finalized the blog, i.e. the XHTML does not validate yet (maybe next week).
