Here is a short list of other blog/cms sites:

Blogs/Journals
• greymatter is an opensource weblogging and journal software.
• OpenJournal from their site "Whether you call it a blog, a weblog, a diary, or a journal, the simple OpenJournal perl script will manage and maintain your Web-based musings and writings."
• Prens@Libre is designed to publish electronic newspapers and magazines, and even utilizes some of the terminology used in the publishing industry.

Portals

• WebAPP which is based on YaWPS but seems to have more activity.
• OpenInteract is a web application environment written in perl and geared to run on the Apache web server using the mod_perl plugin module.
• metadot's Portal Server Platform is an enterprise-wide solution based on open architecture standards.
• Scoop engine take a look at Kuro5hin for an example (with the scoop engine link at the bottom of the page.
• CommPort A "Community Portal" generator that can be tailored for any location.

These are some of the better ones that I've seen, YMMV.

Update:. added Prens@Libre.
