This is the exact same question posted in the regular WP forums but a mod suggested to post here for better guidance.

I am trying to find out which bloggin software is capable of provinding a stable and easy multi user environment. There will be a few blogs from different people e.g. 5 or 6 blogs and there will be one blog which will have 5 authors i.e. a multiple author blog.
Is Wordpress MU advanced and stable enough to give those features? What about the themes for the blogs in Wordpress MU? Can users set up their own themes themselves?
Bloxxom seems to be capable of doing this but the only problem is that it is not as easy to use as Wordpress for authors.
