Vuong (2019) has described a site that aims to improve "the weakest link in the chain of scientific knowledge production", namely the peer review process employed by academic journals.

The site URL is https://scirev.org

Here authors can register to provide their own evaluations of scientific journals they have submitted papers to, so that an author-led rating of journal quality can emerge, based primarily on experiences by authors of the peer-review process.

I recommend reading Vuong's full article, and visiting the SciRev to make your own contribution to assessing  the journals you have had experience with.
