In the future, every phone may have hundreds of apps constantly checking for new information from various sources on the internet. Maybe there should be a standard format in which these sources could send a message to a safe account.
So, if I get a reply on Reddit, Reddit would send details of this to a notification tray in my safe account. Something like
From: Reddit, Content: [x has responded to your post...]. Then the network would distribute this to several notification sub-trays, for my various devices. Then my phone could grab everything from this one source a few times a second instead of checking hundreds of sources every few seconds.
