[Plugin: Contextual Related Posts] Related posts not showing on home page

Related posts are showing up on the individual post pages, but not the home page.

For example, the newest post shows them at the article/post page
(a) http://rockthestatusquo.info/2012/06/06/how-people-shop/
but not on the same article for the home page
(b) http://rockthestatusquo.info/

Is this a setting that I missed? I would appreciate your help.
