It came to my attention that my November 2020 review of Pixelfed was cited to in an article about Pixelfed on the Finnish language version of Wikipedia. You can see a snapshot of the page on June 7, 2022.  My post was cited to for the information that Pixelfed is open source, uses a client-server model, and uses the ActivityPub protocol.  I add a new credential to my resume:  “Recognized expert on free and open source federated social media software and services in Finland.”
