I always found remarkable that whilst the job of all my colleagues boils down to publishing papers, everyone seems so reserved and hesitant when it comes to discussing journals openly.
For instance, rather recently a website was created with exactly that objective, named Journalysis.org. Apparently it seems to have been shut down, as the link doesn't work from my side.
Some specific academic spheres have forums about this, e.g. https://journalreviews.princeton.edu/ranking-peer-reviewed-journals/
Please, can you give me examples of some broader websites or discussion Forums to openly discuss science journals?
