As far as I know… any theme is good for a multi-author blog…
Well some of those magazine themes, particularly Darren Hoyt’s Mimbo, seem to have the author tag already activated. You might want to check that one out. There’s a new Mimbo PRO version, but I believe there’s also a free version still out there for download.

And he goes into some detail here about some of the elements of the theme. You may be interested in #9, Contributors (authors), which you can use to modify any theme to behave this way.

Thank you. I find mimbo very interesting.
I found a theme specially design for multi-authors at http://gluedideas.com/downloads/subtle/ Going to test it out.
