Do group blogs work?

We have several successful bloggers
out of the CLR team… "urn:schemas-microsoft-com:office:office" />

We are now starting to think about
the next level of the team blogging.
Many folks on the CLR team have a concern that they will not be able to
blog frequently enough to make it worthwhile for the readers (btw, how much is
frequently enough). As such we are
considering starting a CLR team wide blog where anyone on the CLR team can
post. The idea is that, although
there will not be a single “voice” on that blog, there will be a constant stream
of useful information.

Has anyone tried this before? Does it work? Other
suggestions?
