I've actually been working on something like this after noticing the job board I had made for myself seemed to extend beyond the set of organizations often considered to align with EA. I figured I'd create a blog to share what I've found while studying EA, so newcomers don't have to reinvent the wheel in tracking this information down across all the different sites. Note: it's still a big work in progress, but I'm happy to share it now given your expression of interest. You can find the board here.
This would actually be really helpful for people new in EA to learn more and catch up on existing discussions and find more thoughtful ways to join the conversation. It sounds a bit like Kialo a platform for rational debate (ex: "ethics of eating animals: is eating meat wrong?"). Would be awesome to see something along the lines of their format for tracking all points around a discussion (but focused only on topics in EA).
