We all know Fakebook is frippery, trivial, and all about retaining eyeballs, and collecting data. The Meta agenda - whatever you use it for. So features are not geared to be helpful outside of that. eg its search engine is egregiously unhelpful in finding a string of words you know you posted a month ago, specifically within a group.

I run two databases for a Charity and images and are available publicly on https://geograph.co.uk which also has charity status (UK legal responsibilities). And the perennial question is how to save and store those images separately. Given there is not a huge mountain of cash available. Then there is the task of trying to tell the committee that all forms of personal storage has an MTBF (aka "use before date"). And 5 years is not being overly alarmist!
