Amazon's move into hosted environments is leaping ahead of Google's dominance of web ownership. Overall Amazon Web Services is pretty cool stuff (the Turk, Simple Storage Service, and more), but the Amazon Elastic Computing Cloud (Amazon EC2) is really cool. I don't know if they're using VMWare or what SAN they're using (StorageWorks? Content Addressed Storage?), but they've got game. Check it out.
I'm not happy with MediaWiki platform for the ConflictWiki, and will be exploring solutions that might be better hosted on a dedicated Amazon EC2 system, or on my very capable ISP.
