Do you have links to your RSS feed from the individual articles/pages? It sounds like you have most of the basic infrastructure in place.

Perhaps you could expand the content on the pages that describe your RSS feeds. Explain to your visitors specifically why/how RSS feeds can be a benefit for them. Education campaigns like that can give your feeds a boost.

Another idea might be to simply increase the size of the RSS logo to draw even more attention to it.
