I would like to see a revitalization of Open Place Reviews or something similar. When I found out about it it was already basically dead. We can already give very detailed tags on the type of restaurant and upload photos of it too but can't leave reviews to my knowledge.

Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.
OpenStreetMap is a map of the world, created by people like you and free to use under an open license.
Join OpenStreetMap and start mapping: https://www.openstreetmap.org/.
There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community/
https://mapcomplete.org/ is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
It does exist another working open source alternative, Mangrove Reviews https://mangrove.reviews/ I think it would be good at least to focus on developing and maintaining one.
As a developer that has used OSM, I want to fix the place classification for nodes in my country. At some point I realized that many region capitals were classified as towns when OSM policy states that they should be cities. It's been on my backlog for the past few months, and I want to dive deeper, understand the classification policy and create a script to fix mistakes.
