I've heard a bit about wordpress mu, and as myself and others I know are all running or hoping to run blogs on the same server, I want to work out if it's worth using mu.
So, the question really is:
What is the lowest amount of users it's worth running mu for?
To me, it's not really about the amount of users. It's about whether or not you want to run multiple blogs out of one code install. That being said, when WP 3.0 comes out, multi-site will be built in. So, if you can wait that long, you might want to just wait.
Running off one install s the main thing here, as only two of us can actually manage WP with any skill, so being able to manage everything though one will be great. Thanks!
You still have to manage each blog form their own backend though. you just have one codebase to upgrade.
