It is an honour to have been interviewed on behalf of the @drfed team for @APC's _Building a Free Internet of the Future_ series. www.apc.org/en/news/drfed-reducing-…

DrFed on reducing complexity and enabling more people to shape the Fediverse

DrFed is a web-based platform for developing and debugging implementations of ActivityPub – an open standard and protocol for decentralised networking. A team of four people from East Asia is developing DrFed. We interviewed one of them, Hong Minhee, regarding openness, tech, technical specs, the Fediverse’s strengths and limits, language barriers to decentralisation, and far more.
