Hello fediverse! https://lib.reviews/ is a free/open/nonprofit alternative to proprietary review sites like #Goodreads, #Yelp, #IMDB.
It plugs into #opendata sources: #Wikidata, #OpenLibrary and #OpenStreetMap (OSM integration is very basic at this point). Still a long way to go but we have a small community and lots of reviews already. On GitHub at: https://github.com/eloquence/lib.reviews - IRC: #lib.reviews on irc.freenode.net - Matrix: https://matrix.to/#/#lib.reviews:matrix.org
