Merging MU into Wordpress is a masterstroke in fairness, as it gives bloggers the ability to build a real community of people working together. Rather than your standard leave a comment and such like it will give the end user/visitor a real sense of contribution to a blog they love.

Just FYI, the MU codebase merge into WP won't change a thing for all the self-hosted WordPress (i.e. single-site) blogs already up and running (or yet-to-be-installed sites, either). Most self-hosted WordPress installs do not have a powerful enough server to run multi-site, as most are on shared-server environments.

The only real change is that current WordPressMU users will, after 3.0 releases, be using WordPress (with "MultiSite" enabled in wp-config) instead of WordPressMU.

The rest of us won't notice any change.
