What?
Why?
How?
...are social networks?
...are they broken?
...do we fix them?
What are social networks?
(Waves hands around)
Ugh. Really? You know, social networks. Why do I have to explain this?
Twitter and Facebook and so on. Google+, I guess.
Instagram? Yeah, Instagram too.
Snapchat? ...Maaaaaaaaybe. I dunno. Wait! I think, yes.
WhatsApp? No, that's different. That's a... messaging platform. It works differently.
Ugh. I have to say why it's different? Fine.
Defining a social network
1. You can create a profile that describes you. Your name or pseudonym, age, gender, your interests, your avatar photo and other photos.

Defining a social network
2. You can connect with other people or groups or organizations to form a social graph.
Each node in the graph is a person (or group or organization). Each edge in the graph defines their relationship.
Edges can be unidirectional (follow) or bidirectional (friend).

@stavy: It looks OK.
@maj: Nothing wrong with it.

Defining a social network
4. Each user has an activity stream. It is a record of everything they've done with the software.
It is usually sorted in reverse chronological order; the newest activities are shown at first.
It includes content they've created, reactions and replies to other people's content, game or app events, changes to the social graph, and other activities.

What's wrong with social networks?
Five pillars of Internet Health
- Open Innovation
- Digital Inclusion
- Decentralization
- Privacy and security
- Web literacy
Open Innovation
OK!
Pros
- Anyone can start a social network
- Many social networks have APIs
Cons
- Rigid terms of service (TOS) on APIs
- TOS changes for business needs of the social network
Digital Inclusion
OK.
Pros
- Anyone, usually, can sign up for a social network
- Platform for self-expression
- Usually good language support
Cons
- Real name policies are bad for trans people, others
- Abuse filters don't deal with bad actors well, and end users can't implement their own
Decentralization
Bad.
Pros
- Anyone can start a new social network.
Cons
- Network effect makes winners grow quickly and losers disappear rapidly.
- Networks rarely allow following or friending a profile on another network.
The network effect
@evanp
@maj
@stavy
@aj
N nodes
N - 1 potential edges per node
N x (N - 1) potential edges in the graph
Edges ∝ N²
100 members = 9,900 edges
1000 members = 999,000 edges
Edges = potential engagement
Privacy and Security
Bad.
Pros
- Social networks have some privacy and security features.
Cons
- Projects like PRISM share social network data with NSA and other snoops.
- Advertising model shares social data with marketers.
- Large number of users make social network software an attractive target for hackers.
- Business model encourages breaking down privacy.
Web literacy
OK.
Pros
- Users can create content.
- Users can read content.
Cons
- Fake news
- Silos discourage leaving the social network to go elsewhere on the Web
How can we fix them?

ActivityPub
A protocol for the social web
Profiles
Using Activity Streams, a profile is just a Person or Organization object, available at an URL.
The URL of the object is the profile's ID.
Social Graph
Every profile in the network has a property that lists all their social connections, which are also Person or Organization objects.
The social graph is distributed.
Content
Using Activity Streams, to create Note, Image, Audio or Video objects.
Reactions
Every object and activity has a property that lists its reactions and replies.
Every action has a property that says what it is a reply to.
Activity Stream
Every profile has a stream of activities that the person or organization has done.
Incoming Stream
Every profile has a stream of activities by people that they follow or are friends with.
