using the memento mediawiki extension to avoid spoilers
DESCRIPTION
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.TRANSCRIPT

The Problem
Wait, he’s dead?
How do we avoid these spoilers?
We haven’t caught up because of a job/ailing mother/bar crawl/life.
Current “Solution”Post a big SPOILER ALERT on the page
I haven’t caught up. Is this Wiki even useful to me until I catch up?
I’m afraid to use this site now.
Site owners may be losing ad revenue because visitors turn away.

DEMO Screenshots
We want to find information about Kevan Lannister, but haven’t read the book A Dance with Dragons yet. We set the Memento Chrome Extension prior to the release of that book: June 29, 2011.
DEMO Screenshots
We use the Memento Chrome Extension to request a revision of the page close to, but not over, our requested date.
DEMO Screenshots
And we get the revision of the page closest, but not over, the date requested.
DEMO Screenshots
And, as you can see, this revision of the page has no information aboutA Dance With Dragons.
DEMO Screenshots
And that’s not all… I can browse the rest of the site, spoiler-free.
DEMO Screenshots
Here’s the past revision of the page about Tommen Baratheon, as linked to, from the Kevan Lannister page, and still close to, but not over, our requested date.
