A touch of the exotic, from Switzerland : ELOG
Not as well know as their cheese, chocolate, gold bars, Victorinox knives and luxury watches, but nice and useful too, and free :-)
Read up on ELOG here :
http://midas.psi.ch/elog/It's a versatile, 'batteries-included' weblog app (no separate web server or database needed) that can be turned into almost anything (blog, forum, note-taking, database etc.). Very simple to configure. Can replicate or synchronize between ELOG servers, & much more.
To try it out: grab the tar.gz archive on the site above (no IPK yet, sorry) and follow the Linux install instructions except for the "make" part.
Then get the ready-made binaries for the Z here :
