postActiv is a free software project to develop a social networking platform. It is derived from GNU Social, which is itself derived from StatusNet and Laconica. It helps people in a community, company, or group to exchange short status updates, do polls, announce events, or other social activities. Users can choose which people to "follow" and receive only their friends' or colleagues' status messages. They can also view the public timeline of the site to see everyone, or the "whole known network" timeline, to see all the people in sites that have connected with this one, by someone following them. It provides a similar service to proprietary social network sites, but is decentralized, and with many additional features and an open, free software codebase that you can develop your own plugins for, it is much more awesome.
Using plugins available to postActiv, status messages can be sent to mobile phones or pages, instant messenger clients that implement XMPP, and desktop clients with support for the Twitter API. It is also compatible with plugins developed for GNU Social.
postActiv supports an open standard called OStatus https://www.w3.org/community/ostatus/ that lets users in different networks follow each other. It enables a distributed social network spread all across the Web.
postActiv is derived from GNU Social, and GNU Social was originally developed as "StatusNet" by StatusNet, Inc. with Evan Prodromou as lead developer. It is forked form commit bd306bdb in the Nightly branch of GNU Social, available here: gnu/gnu-social@bd306bdb
It is shared with you in hope that you too make an service available to your users. To learn more, please see the Open Software Service Definition 1.1: http://www.opendefinition.org/ossd
