I really enjoyed using blosxom and even had an instance setup for work in our internal site. It was amazingly simple in concept and implementation. One downside was that blog entry dates were based on file timestamps, so if a published entry was ever edited, that entry would be considered the newest entry. Their site and documentation has kind of fallen into disarray as well.

I'm rolling my own solution for personal use that has minimal dependencies and does personal journals right. It uses TT, flat files, Markdown, and unix utilities to get the job done. A perfectly glued together blog system :)
