ios8-share-extension

I want to implement an app extension, but I can't decide if I should implement it as a Share Extension or Action Extension. The documentation doesn't say much about the differences, just this: Share (iOS and OS X) : Post to a sharing website or share content with others Action (iOS and OS X; UI and non-UI variants) : Manipulate or view content originating in a host app Are there technical differences as well (e.g. does an Action extension allow me to do something that the Share extension doesn't), or is it merely a convention Apple wants you to follow to make things less confusing to users?
