Business Blogs we took blogging to the next level by creating powerful self-hosted software that anyone could install and have a blog within minutes.
Now with MU we're making it as easy to create a thousand blogs as it was to create a single blog with Business Blogs 3 years ago. By building on the base of Business Blogs and syncing development, we get the benefit of the huge ecosystem in plugins and themes that have developed around the project.
Development on MU is spearheaded by Automatic, since they use MU to power Business Blogs a great deal of the companies resources are poured into improving the code, and it all goes back into the open source world via MU.
If you'd like some background on the Business Blogs project, check out its about page. Since Business Blogs and Business Blogs MU share 99% of the same codebase, the features and development on one also benefit another. As Business Blogs is used by everyone from Yahoo to the New York Times, it isn't going anywhere.
