I mentioned it in the comments on the article, but I typically just make my Wordpress blog use the same database as my Rails app. Then in the Rails app you can create a BlogPost model or whatever to use anywhere in your rails app.
You can either install the WP app on the same server as your Rails app, or you can just create a custom user and SSH tunnel for your DB between the DB server and the WP server.
Julien from Superfeedr here. Please get in touch wit any issue/question you may have. I'm sorry Micah had so many issues and I'll try to help him find his way.
