Here’s a business idea: long term storage. And by long-term, I mean 5, 10, 20, 50 years. The economics change. I don’t want to pay 12$/month. I want to pay x$ now to have my pictures stored for posterity, long term. So I can order them in 20 years and have a reasonable chance of getting them.
The technology changes too. If you don’t need fast access, you could store on offline dvd’s or something, instead of on connected storage like harddrives. It’d be an interesting challenge. I wonder if you can make it cheap enough.
