It depends on what you use EC2 for. The experience I'm talking about isn't "with Linode". The experience is with taking a distribution that has none of the parts of the typical LAMP stack installed and installing and configuring them properly for the solution that you are providing.

Now experience with EC2 in provisioning many machines of the same configuration using something like Puppet or Chef is a related but separate thing, and is also good to have, but you have to be able to walk before you can run.
