Ok, so I have a client wanting to build out a few sites utilizing the Buddypress social network features. Now that WP 3.0 has been release, which seems to make using MU a thing of the past for Buddypress, do I do it the new way with 3.0 (but it's still a new release with some issues to work through) or do I do it the old way with MU and Buddypress?
