I love this idea, was thinking about how nice something like this would be myself. Sad it'll get no chance because of people going "muh nazis", even though it will work with any URL. It appears theres this assumption that it will be used for politics related stuff which i have no concern with myself. No neonazis will be gathering on the URLs that are meaningful to me and id say most people. Read.write.as blogs/posts have no way to leave comments and feedback, so something like this would be cool. If i wrote blogs there, id like to see feedback and supportive comments if possible. And since its an external function from the site itself, i can either grow a skin or uninstall the addon. It just works.
