We should put all possible changes/reforms in a big list, that everyone can upvote/downvote, agree disagree.
EA is governed but a set of core EAs, so if you want change, I suggest that giving them less to read and a strong signal of community consensus is good.
The top-level comments should be a short clear explanation of a possible change. If you want to comment on a change, do it as a reply to the top level comment
This other post gives a set of reforms, but they are a in a big long list at the bottom. Instead we can have a list that changes by our opinions! https://forum.effectivealtruism.org/posts/54vAiSFkYszTWWWv4/doing-ea-better-1
Note that I do not agree with all comments I post here.
Peer reviewed academic research on a given subject should be given higher credence than blogposts by EA friendly sources.
Really depends on context and I don't recall a concrete example of the community going awry here. You're proposing this as a change to EA, but I'm not sure it isn't already true.
If you compare apples to apples, a paper and a blog answering the same question, and the blog does not cite the paper, then sure the paper is better. But usually there are good contextual reasons for referring to blogs.
Also, peer review is pretty crappy, the main thing is having an academic sit down and write very carefully.
