Amber is a nifty solution to the problem of dead links in blogs and websites. "It automatically preserves a snapshot of every page linked to on a website, giving visitors a fallback option if links become inaccessible." By default you store the snapshop locally, but you can also store it in the cloud, for example, using the Wayback Machine, Perma.cc or Amazon web services. It's available as a plug-in for WordPress and a module for Drupal. There are also modules for Apache and Nginx (with local storage only). No word on the copyright implications but I can't imagine the commercial media will be pleased.
