Drupal is amazing in how it simplify things for developers. I’ve recently tried playing around with some RSS feed to post conversions, and ended up writing my own. As an example I set up http://www.freelancesoftwaredevelopment.co.za/. This module checks up on RSS feeds every 15 minutes and then updates the website automatically. This way you are able to automate the posting of new content to a site.
The site is still a work in progress, and is more there for a proof of concept than anything else. Things like making the descriptions of the RSS feed items display better is in the works.
