Diaspora is a nonprofit, user-owned, distributed social network that is based upon the free Diaspora software. Diaspora consists of a group of independently owned nodes (called pods) which interoperate to form the network.

The social network is not owned by any one person or entity, keeping it from being subject to corporate take-overs or advertising. In September 2011 the developers stated, "...our distributed design means no big corporation will ever control Diaspora. Diaspora* will never sell your social life to advertisers, and you won’t have to conform to someone’s arbitrary rules or look over your shoulder before you speak."

This illustrated user guide is useful to understand key differences and features in Mastodon, including detailed howto information.

Mastodon is a social network application based on the ActivityPub protocol. It behaves a lot like other social networks, especially #Twitter, with one key difference - it is open-source and anyone can start their own server (also called an "instance"), and users of any instance can interact freely with those of other instances (called "federation"). Thus, it is possible for small communities to set up their own servers to use amongst themselves while also allowing interaction with other communities.
