This seems... at least superficially worse than status quo? I don't see how this helps.
LessWrong currently has posts and tags. I do agree it doesn't make it that easy to find a relevant post and open question. But how does spreading out the questions across a sprawling unstructured group of subforums help?
(FYI EA Forum experimented with building subforums. My impression is it mostly didn't work out the way they hoped)
I'm interested in hearing more about what problems you ran into though and what specific things you're hoping for. Like what are some actions you took recently that didn't work, and what actions are you imagining taking on the new site that go better?)
Coming here for the first time I immediately noticed how unstructured the platform is. Imagine AI Alignment creating a brand new platform - or recreating this one if you prefer - that is structured exactly like Reddit. I mean exactly like Reddit. That way the many thousands of open-source developers out there working to solve the alignment problem would know exactly where to go to find the open questions in each category of development, and to also ask for help where they are stuck. Guys, this is a no-brainer. The way you have it now you make it so much more difficult for people to find questions and answers on the part of AI alignment that they are focused on.
