Jason Scott's Protection From Online Eviction? and his follow up post make the argument that services like AOL, MySpace, flickr, or Skype should be treated like landlords.
The power landlords have over tenants is overwhelming, unless restricted by law. The argument: if they want to shut down a service, essentially evicting users, they should be required to give notice and keep things running for a year.
This would allow people to safely migrate their digital objects like photos and videos and blog posts, renew relationships with people in their contacts and agree on where to move, file change of address notices for their businesses, and otherwise minimize the logistical, economic, political, emotional, and familial havoc forcible ejection can create.
