There are several plugins to automate your blog content. if you own a domain and don’t want to park it, or just need to fill some content in a blog for other purposes, you can do it quit easy with this list of plugins, some more complex and others easier to use, but all of them have the basic feature of creating content to a wordpress blog by automate the write post procedure while using rss feeds.
Actually i used this one on several blogs i owned and i really recommend it, you can automate all the content creation process and also have the option not to auto publish but to read the posts first and only publish them yourself.
FeedWordPress is an Atom/RSS aggregator for the WordPress weblog software. It syndicates content from feeds that you choose into your WordPress webblog; if you syndicate several feeds then you can use WordPress’s posts database and templating engine as the back-end of an aggregation (“planet”) website.

Tried this one a few times, this is my second choice because of not being as friendly as the other two. i liked the ajax interface though.
WP-o-Matic makes autoblogging a snap by automatically creating posts from the RSS/Atom feeds you choose, which are organized into campaigns.
