10.6. You’re Multiskilled

Multisite enables you to consolidate the management of multiple WordPress sites into a single installation, and is an extremely useful tool that appeals to two primary user groups: people who want to streamline the management of multiple WordPress sites, and people who are interested in developing diverse communities of blogs the way Automattic maintains on wordpress.com.

Beginning its life as a separate project in the WordPress universe, Multisite was merged into the WordPress core as of the major 3.0 release. While an incredibly feature-rich set of functionality, Multisite is currently in a heavy stage of development as a core WordPress component, and is not enabled by default in any given WordPress installation. However, if you are willing to roll up your sleeves and get dirty with Multisite, its benefits are potentially extremely rewarding.
