WordPress.org originally used miniBB for its support forums, because it was one of the lightest and fastest bulletin board scripts out there at the time (2003’ish). After a hosting change and PHP upgrade broke the forums completely, something needed to be done right away.
So the day after Christmas in 2004, Matt started coding and two days later the first version of bbPress was pushed live on WordPress.org. Since then, Michael Adams joined, then Sam Bauers, and in 2010 John James Jacoby reinvented bbPress as a WordPress plugin.
bbPress continues to grow alongside the entire WordPress community, and is the world’s most widely installed open-source forum software.
The vision of WordPress is to democratize publishing, so then the vision of bbPress must be to democratize discussion. Every decision we make towards the future of bbPress is with that in mind.
