propeller is really great but the pr of 7 may be a bit misleading. That is say you go to propeller and submit a story, you will get a link. The link will not get the pr 7 juice but something more like a pr 3 or pr4.
Either way, i do agree with you that propeller is a really cool place to post your stories/articles to and traffic will get a boost. In addition, the customer service there is really great.
