With this WordPress Plugin you can “automatically post to your Wordpress blog from an RSS, ATOM, or other XML feed”.

This plugin is potentially dangerous: it converts xml into Wordpress posts. It could be used to run an aggregator site, or it might be used by spammers to push high-profit keywords into their blogs. I’m not sure if writing a Wordpress plugin to automatically post from RSS will enable spammers a “5-minute” spam blog installation or not. However, I think that it’s useful in its own right, and helped me learn a little more about RSS.

I am currently testing the plugin out over at Green Blog. You can download the plugin and read more about it over at elliottback.com.
