Project Steve Guttenberg is a PHP-driven
diary/journal/blogging application that integrates
seamlessly into an existing Web site. It provides
many of the core features (including comments,
trackbacks, RSS 2.0, tags, and searching) and
administrative controls (all Web-based) of other,
larger systems, but doesn't use a database, is
XHTML 1.1-compliant and its look can be completely
customized via CSS. It can easily be scaled to
host several journal sites with a single
installation.
