b2 was the precursor to WordPress. Also written in PHP for use with MySQL, b2 was originally developed by Michel Valdrighi, who is now a contributing developer to WordPress.
Though WordPress is the official successor, another project, b2evolution, is also in active development.
Beginnings of WordPress
The name WordPress was suggested by Christine Selleck, a friend of lead developer Matt Mullenweg.
WordPress currently supports one weblog or site per installation, but there is a multi-user version available called WordPress MU. Even with normal WordPress, a user can still have more than one WordPress blog in the same server, even on the same database, by placing the files in different subdirectories.
WordPress releases are named after well known jazz musicians (e.g. Mingus).
