I want to mantain a local static html blog system on my local

Is there any special function for me to use org as blog system?
I need a reference to start......
With the following Ikiwiki plugin, I have been using org as my
Ikiwiki input mechanism (so I write all my blog posts as org-mode
files, and Ikiwiki transforms tehm into html and rss.

eats your blog:)
Ian.
