* There is an enormous quantity of culture locked into Facebook posts
* Since Facebook's graph API have been shut down, there exists no API-based way to export _other people's data_. You can get whatever you personally have posted to FB, but none of what _other people_ have posted.
* Individual posts might be scraped, and present in archive.org ,but people's / pages' indices are not available for non-logged-in users
* Social networks have a typical lifecycle of 5-10 years; and their shutdown can happen in a very short timeframe, see eg. geocities ; but imagine that without any accessible index, making full archiving impossible
* This implies, that if/when FB goes down, so will a major slice of Internet Culture circa 2008-2016
* If you have any suggestions, or partial solutions to this, please kindly post it to http://softwarerecs.stackexchange.com/questions/37036/self-h... .
