From that, you learn just one thing: Next time, I should consider that response. Or, on a more basic level: Next time, play a different move.
Maybe, but even for beginners, it seems to me like that you just don't learn very quickly that way. For example, if a new player looked at hyperpape's position from last page, studied it for a minute, and didn't realize that A was a threat to capture, then on one level, they might learn: "Next time, I should consider A!" That's fine as far as it goes...
...but if they are surprised they didn't see A, and they think about why they didn't see A, they might learn: "When I have a couple stones clumped up that are surrounded on three sides, they might get in trouble, even if it looks fine at a glance. I should double-check potential moves there to make sure they are really OK." That is the kind of thing to learn that
really pays rent.

Definitely -- but that doesn't sound to me like the kind of thing you are thinking very hard about if you are only taking ten seconds per move!
Let me give an example from my games, which is a pretty basic example but not a beginner example: A few weeks ago I played a game and I did one of those 3-4 approach josekis where you jump out and the other guy jumps out along the side. I had the opportunity to play A:

in a situation where it would have sealed black into the corner fairly securely. A stronger player pointed out to me afterward that I didn't play it, although it was very big. Since I had taken some time on the game, I knew that I had considered it, but didn't play it because I thought another move on a different side was bigger. When I looked at it, I didn't see why it was big in this case, but after playing out some variations in review, I could appreciate that white got a lot of power by sealing black into the corner. So I learned that I might be intuitively underestimating the value of sealing in a group like that, and I should think twice about it next time when I see a similar opportunity.
A few games later I encountered this position as white after starting on 3-3:

I don't usually play 3-3, so I had not seen this move before. My initial instinct was to tenuki, because there were some other moves I wanted to get, and it looked like my corner stone was still safe. But then I remembered my previous experience about seeing the value of sealing stones in, so I gave a second thought to analyze what would happen after black followed up with A or B. After looking at it, I decided it was important to not allow that, so I played A, which I think was a much better choice in that situation.
That is the sort of thing which I could not learn very easily if either my first game or my second game was a blitz game. It would take a lot of experience to teach me the same lesson if I hadn't stopped to think about it.
