Word Press sets these algorithms to try to steer you toward what they want you to see. The Intuitive Categories should take you to Categories not tags but they’ve set the science search on the science category to tags. Why? Not.
There are 600 great posts on here under science. USE THE SEARCH BOX AND TYPE IN SCIENCE and the posts will be in chronological order.
I’m not done categorizing and tagging but making a good dent. There are 750 posts left to categorize.
