Hi.co, a website that allows its users to post “moments” with a photo and annotation, plans a similar trip to the distant future. The operators, Craig Mod […] and Chris Palmieri, announced today that the site will freeze service in September 2016. However, all posts present in the site’s database at that time will be microprinted onto a two-by-two-inch nickel plate. The entire site-2,000,000 words and 14,000 photos-should fit on a single disk. Several copies will be made and distributed across the globe; the Library of Congress has already been secured as a repository. The plates have a lifespan as long as 10,000 years, and they may be viewed with a 1,000-power optical microscope.
