rbutr – Facilitating Online Discussion
http://rbutr.com/

rbutr is a community driven app which creates links between webpages where the content of one page is a rebuttal against another. The content may be directly arguing against the original content, or generally presenting contradictory evidence. App users are alerted when they browse a rebutted page, providing them a link through to the rebuttal(s). rbutr aims to facilitate inter-website debate, guide users to rebuttals of dubious information, and indirectly influence our users so that they approach all online information with an increased level of skepticism and critical appraisal. This will be added to the tools section of Research Resources Subject Tracer™ .
