If you can take yourself out of your first world techie social media smart-shoes for a second then imagine this: you're 53 years old, you've been in prison from 20 to 26, you didn't finish high school, and you have a grandson who you're now supporting because your daughter is in jail. You're lucky, you have a job at the local Wendy's. You have to fill out a renewal form for government assistance which has just been moved online as a cost saving measure (this isn't hypothetical, more and more municipalities are doing this now). You have a very limited idea of how to use a computer, you don't have Internet access, and your survival (and the survival of your grandson) is contingent upon this form being filled out correctly.
Why libraries matter: a great comment at MetaFilter.
