The news first broke back in July, at WordCamp. Matt Mullenweg, the founder of WordPress (and parent company Automattic) [Correction. Please see the comments.] told the audience that WordPress (the .org) and WordPress MU would be merging. Until today, though, little else has been heard about it.
In the most recent WordPress Beta announcement, for 3.0 Beta 1, there is a very small note that almost gets lost in the context: “The merge! Yes, WordPress and WordPress MU have merged. This does not mean that you can suddenly start adding a bunch of new blogs from within your regular WordPress Dashboard.”
The line goes on to say that there are some instructions to follow in order to access the more in-depth features of Super Admin, but nothing else is noted in the post.
What this means for the rest of us is that we can now run multiple WordPress sites from a single installation, just as users of WordPress MU have been able to do in the past.
The Next Web is a great example of the MU capabilities. Each of our Channels is its own WordPress blog, allowing us to post on any or all of our Channels at any time.
Giving these features to all WordPress users not only hands some massive content creation ability but it also helps to cement WordPress even more firmly into the foundation of blogging.
