I tried all sorts of webloggers (blogger, tkblog, etc.), but in the end the easiest one to install and use was the one you are currently seeing.
GreyMatter has the big advantage of being just a set of perl scripts that live (data and script) in the cgi-bin directory, no requirements to the environment but that there be a perl shell available.
If you like this, I strongly encourage you to use it. GM beats anything else I have seen so far!
