I have found everything posted to be edifying, and I look forward to more. My impression is that there is not a lot of disagreement among experts about what is true and what is uncertain in the topic. At the same time, when some experts -- not just bloggers -- engage the lay public, in "campaign mode" they can be less than candid on some matters of importance.
