The rise in fan-based wikis allows fans to discuss TV shows and books in ways never before seen. Unfortunately, as fans, we have the problem of spoilers. Using a fan-based resource is wonderful for those who are current with their reading/watching, but it is frustrating for those who want to experience the suspense of reveals but have not caught up yet. Some sites have even added warnings to their pages to indicate the existence of spoilers, but these effectively tell visitors who are behind on their fiction consumption that the wiki cannot be used by them until they catch up. RFC 7089, also known as Memento, provides a user the ability to choose a date and time in the past, then allows them to browse the web and see how it looked on that date. One of the great use cases of Memento is the avoidance of spoilers. Though Memento was original designed with the Internet Archive and other web archives in mind, these archives do not have all of the past versions of a page, subjecting fans to missing information they otherwise would have had access to, if all revisions of a page were available. Jointly developed by Old Dominion University and Los Alamos National Laboratory, this is where the Memento MediaWiki Extension comes in.
