Hello,
I just made a bot which notifies about new SDG Blog post on Mastodon and other ActivityPub based federated social networks (AKA The Fediverse). You can follow it here or as @unturned_blog@botsin.space
If you haven’t heard of Mastodon yet, it is like Twitter, but has no centralized server. Which means that a user from mastodon.social can follow, reply and boost (=retweet) posts of user from fosstodon,org like you can send an email from outlook to gmail account. Thanks to standardized protocols a mastodon user can even comment or like videos on any peertube server (decentralized youtube alternative).
