Arguman.org

en.arguman.org is basically an argument analysis platform. I think we can say a different and new type of social media platform. It's very similar with graph tree. So, platform use argument map. Argument mapping improves platforms ability to articulate, comprehend and communicate reasoning for critical thinking.

You can watch evolution of en.arguman.org on this video. Platform act like a graph tree and video is really good, and time-based.

Also you can watch a video about platform from founder Fatih Erikli.

It can be little bit difficult to understand and be adapt to platform. Because I never saw this kind platform before. But when you spend some time on it you'll like it. Platform is an open source project. So, you can support them on their github page or donate them on pay pal.
