Blosxom, kind of
During one of my chats with dj, he mentioned blosxom. Blosxom is lightweight Weblog application. Very simple and elegant and written in Perl.
I like perl, but mostly use PHP for my web applications. This got me started to reimplement the idea of blosxom in PHP, while using the same input: .txt files with the first line being the title. This has the advantage that I can still use blagg and it's nice plugins. Let's see how this works out...
At this moment it just reads the directory for the blog files and displays them using Smarty templates, like the rest of my site. There is no support for syndication yet, but since it uses templates anyway, it should be fairly easy to do that. Also the 'archiving' feature of blosxom is not implemented.
