I think Utopian.io is a platform that gives everyone the opportunity to create a Contributor Report. Like suggestions and also criticism or ideas for open source development

The Contributor Report is a post automatically entered in the "utopian-io" category, where you can write the latest contributions you make to the Open Source project, considered with reviews and rewarded like votes. Contributions can be anything, from code development to graphic design, documentation, social engagement and more.
Thanks
