1. Use the Scoop.it widget
It allows your readers to see your latest posts. You can easily configure and install the Scoop.it widget here: http://www.scoop.it/goodies. Follow the tutorial to learn how to make it work.
Note: WordPress doesn’t allow the iframe tags, for this reason the Scoop.it widget will only work properly on self-hosted blogs.
2. Use the sharing options
Another option is to share your posts from your topics or another user’s topics if you’ve connected your WP/Tumblr accounts. Click here to do so: http://www.scoop.it/share/configuration
