I’m new to Lesswrong, but really happy to find you writing about CollAction—which i set up with a few friends a while ago. I think your suggestions are really great—thanks for that! Some are very much in line with our own ideas, but we simply haven’t had the resources yet to implement it (we’re all volunteers and we’re spending quite some time and energy on other project like the Slow Fashion Movement, which spun out of collaction.org as the most successful crowdaction and started to live a life of its own) .
So, if there’s a community here that would like to build such a platform, I would say—let’s have a chat to see if we can just use collaction.org as a basis and build upon that. Feel free to reach out if interested
Cheers—really great stuff in your post.
