clikkit provides in-window framed browsing that is well-suited for viewing multiple links without navigating away from the current page (works best with a widescreen monitor).
It is available as a jQuery plug-in (http://msssk.bitbucket.org/) and as a Chrome extension (https://chrome.google.com/webstore/detail/beoobakjmicjpifdpcbfdgifhimhpnen) with support for HN, reddit, hubski, and Google search results (experimental).
