Instead of setting up a longer living backup for each case, it would be interesting to setup a generic storage mirror and a corporate foundation that can keep these sites alive.

When a startup shuts down a product, they can donate the domain name or point it to the mirror to keep it alive.

Something like archive.org, with some donated servers and a couple of people working on it.

Twitter and other acquirers usually only want the team, and this is happening more and more. We are losing large parts of the web. I wouldn't be surprised if less than 1% of Posterous is exported and goes to live on in other forms. Either way the URLs and links all die.

I've been keeping reocities alive out of pocket. It costs a few hundred every month in hosting costs and another few hundred in machine write-offs. I got about .37 in bitcoin donations, so I'm a bit short still :) But I think it is well worth doing. I assume hosing posterous would cost a lot more than that so I'd have to find some funding but I'm pretty sure this could be done.

I'd be more than happy to help out if Twitter are willing to do it with Posterous. Register a non-profit and then go out and approach some of the larger co's for funds and/or resources to keep it running forever.

Make static backups of these sites using their sitemaps[0] and then ask them to donate or point their domains

Hm, that sitemap seems to be limited to 10K entries and it isn't clear how it links to the next level sitemap. I'll get to work on this.
