Cats! You can always post cats! Now, on a more serious note: you could host your friend's sites (and probably can do a split of the payments), use it as a host for various tests (if you are a developer). If you are living in a non US country you could make an instance in US then use it as a proxy to access various services that requires you to be in US (hulu, netflix, etc)
