I often see great reviews and am curious what else they'd reviewed and what they had to say but seems impossible. There's a user name, and # of reviews but neither clickable.

I had (and still have) that query too. I don't know if there is a way to see/read someone's reviews. Or even mine.

Because users themselves can't even query it. Heck, their review isn't even a sticky pinned so they can see.

And they can't be edited, updated, deleted, or modified without quite a lot of red tape.

It's very strange. On Steam it's possible and cool. You see a good reviewer (or bad one) and naturally I'm interested in what they've had to say about other games.
