There is still a social aspect of Lifeed but its very minimal. Users can only post videos that they have captured themselves and there is no other content permitted in the public feed.
The “APPEARANCES” section is where all of the videos you appear in are found. This includes videos from your friends or friends of friends as well as videos fed from strangers that you have been recognized in via your serial code that each device can pick up on. The only way to view the video from someone you don’t know, such as a stranger on the street that you passed by or someone who sat next to you on a plan, is if they have been posted into the original persons public feed or when their 5 Year Feed has been published.
Every 5 years users are required to publish the feeds from 5 years prior. For example, in 2045, all users will be able to explore every video and tag created from the years 2035–2040. These videos can be found under the EXPLORE tab and can be saved to a collection.
