+## Cool ideas
+
+We got feedback from cool people and have collected the ideas around:
+
+* https://github.com/ont-app/vocabulary - a cool way to map clojure namespaces to linked data cotexts.
+* https://github.com/lambdaisland/souk - a poc reading jsonld from mastodon & provides a small webserver having the webfinger-protocol
+* https://www.youtube.com/watch?v=cru7E96pLAM - youtube series for implementing the souk poc
