OERu Social Network

OERu hosts its own social network using Mastodon for course specific activities and a backchannel for the Learning in a Digital Age community. A backchannel is a networked conversation that runs alongside the primary course conversations. You will need to know how to use the course hashtag in your toots for course related posts. 

Note that Saylor Academy's LiDA100 course combines all four of the OERu micro-courses. This Saylor course will use four hashtags for the backchannel: #lida101 for unit one conversations; #lida102 for unit two; #lida103 for unit three; and #lida104 for unit four.

What is a Mastodon Social Network?

Mastodon is a federated social network that uses microblogging features similar to Twitter. As a federated technology, it is administered independently across many open source software servers around the world called instances rather than a single corporate provider. The OERu instance of Mastodon is hosted at mastodon.oeru.org.
