What is "greymatter"

Greymatter is a free and open source blogging software package, originally created by Noah Grey in November 2000. It was "the original opensource weblogging software." Noah Grey stopped maintaining it around 2002. Since then, it has been maintained by the community of users. It is one of the first software packages created for blogging, and had a large number of users. With the creation of WordPress and Google's Blogspot, its users have declined since 2005, but it is still in use.

Greymatter does not require a database; its only requirement is Perl support on a webserver. It features robust options and extensibility, with a focus on customization and user control. Its current version is 1.8.2.
