I host on Appfog because I don't trust the history of AWS East, and want the option to migrate my app to rackspace in the event AWS East is down (or performance impacted).
I run an app on Appfog, hosted in AWS East and not Rackspace due to Rackspace not working! Have contacted support about deploy issues and uptime issues a lot. They always respond that I shouldn't be using Rackspace because 'its in beta'. No wonder adoption is low! Either this is one hand not speaking to the other, or they gave up trying to get things to work on rackspace, and this is their self-created excuse to drop support for it.
