MetaRho is a basic blogging app I use for my site. I am incorporating code and extensions to better support tagging, linked data and general semantic web interaction.

The application itself is simple enough and sufficient for anyone looking for a basic blogging app. More likely there be some code examples some folks may find useful or interesting.

You shouldn't, go use Wordpress. No really, go use Wordpress. It's a great blogging application that's easy to use, has a number of plug-in and easy to theme.

Still here?

Alright then, it's possible you might find MetaRho useful if you really have a desire to publish to the web and have it backed by strong structured data like RDF, RDFa and other formats like ATOM and such.
