Changes

Nowadays, people peoples' personal connections are spread across multiple online services (Facebook, Google+, Skype, etc). These services usually already have done the work of ensuring both people want to see each other's presence and have ways to facilitate a conversation. All they need is a way to be aware of a users presence when their app might be closed or suspended (on a phone). By serving as the underlying plumbing notifying AppService's when users are online, Mozilla Presence avoids having to try and change users expectations about where their 'friends' are and can facilitate new social interaction applications that need presence data.
