Looks like good stuff, but honestly I worry that Wordpress is getting too bloated. Merging Mu into with standard Wp along with integrating new features (that used to require plugins) might make it more convenient for a power user - but for so many people it's getting complicated. I've switched to using Mu for all of my domains, hosting them off the same set of files (imagine the plight of the poor chap upgrading 70 installs), so I'm glad to see the integration but then again... now for simple sites there's more files, more code to parse and more bloat. It really pushes me towards writing a small CMS that does just what I want, since the "simplicity" factor of Wordpress is going the way of the dodo. It brings back memories of Joomla.
