An open source social network development platform. Introduced in 2016, Mastodon allows anyone to create a social networking feed similar to Twitter and Tumblr. Although there is a 500-character limit, each Mastodon instance is developed, controlled and moderated by the entity that creates it. Users may communicate only with others in their community or follow users in other Mastodon communities.
Truth Social - Truths and Re-Truths
One of the most high-profile Mastodon-created platforms is Truth Social, which is run by the Trump Media & Technology Group (TMTG) and Digital World Acquisition Corporation (DWAC). Launched initially for iOS users on Presidents' Day, February 21, 2022, Truth Social is a rebirth of Donald Trump's Twitter account which was deleted on January 8, 2021. Tweets are called "truths," and re-tweets are known as "re-truths." See social network
