It’s true that there are tons of blogging software solutions from which to choose. Each has their place, and their legion of ardent followers.

Habari is being written with a firm understanding of the current state of blogging. Most other blogging packages have been around long enough that their responses to things like comment spam and Digg site overloads are bolted on after the fact; whereas Habari is being written from the beginning to take these things — and more — into account.

Habari strongly favors open, standard, and documented protocols. Atom, being both open and documented, is the prefered syndication format, and the Atom Publishing Protocol is the prefered means of remote communication with your site. This is a core feature, and not a plugin.

Habari is being written specifically for modern web hosting environments, and uses modern object-oriented programming techniques. Using these recent but well-established additions to the PHP language allows Habari to make use of PDO, enabling prepared statements for all interactions with the database. This greatly reduces the system’s vulnerability to SQL injection attacks. This is just one of many benefits of modern object-oriented techniques.

Those are just a few of the technical differences, but a major component of what makes Habari different is its community participation model. Users who demonstrate a consistent level of quality contributions to the project are granted more privileges within the project.
