Nice article on upcoming WordPress 3 at Wpbeginner.com WordPress 3.0 is projected to be released on May 1st, with Feature freeze set for March 1st.
“You can now have multiple sites in one installation. For example we can have showcase.wpbeginner.com with one WordPress installation if we want. What are the possible outcomes? If you have one site now, and you do not want to add more sites later that is perfectly OK. Nothing will change for you. If you are running on WordPress MU, after the upgrade your sites will remain the same. Nothing will change for you.
The bottom line is that nothing will change if you don’t want it to change. This feature is just an add-on that will help users who want to have multiple sites. It will also help WordPress MU users because this will allow them to use all WordPress.org plugins without hacking them.”
