A true Web3 Tweet. For the first time, platform users can own their own data and accounts, and have an unquenchable voice. Not only is the app open-source, but it also an open platform, where users can set up their own servers and join the network. The first server node is a Raspberry Pi in my home. As more users join, a Web3 social media platform will be created by the people and for the people.
