Stability is the key in SEO. Therefore, if you maintain some rotating content on your website that can only harm and not work for your optimization anyway.
Sorry, that is just not true. We do it on a significant number of our sites, always to good effect. And I've helped numerous clients with this also. Again, as long as it's a modest percentage of the page's total content, then exposing more content off the homepage gets visitors more involved with more of the site, leads to more deeplinks, increases involvement and stickiness, blah, blah, blah.
