Overview
WordPress started in 2003 with a single bit of code to enhance the typography of everyday writing and with fewer users than you can count on your fingers and toes. Since then it has grown to be the largest self-hosted blogging tool in the world, used on hundreds of thousands of sites and seen by tens of millions of people every day.
WordPress is an Open Source project, which means there are hundreds of people all over the world working on it. (More than most commercial platforms.) It also means you are free to use it for anything from your cat’s home page to a Fortune 5 web site without paying anyone a license fee.
Ever dream of running hundreds of thousands of blogs with a single install of WordPress?
WordPress MU, or multi-user, is designed to do exactly that. It is most famously used for WordPress.com where it serves tens of millions of hits on hundreds of thousands of blogs each day.
Who is WordPress MU ideal for?
- Newspapers and magazines, like Le Monde.
- Universities, like Harvard.
- Blog networks
- Niche-specific blog hosts, like Edublogs
