I think there's a difference in what people are saying and what you are saying. I'm not sure people miss seeing stones in atari often, when their opponent plays the move that puts the group in atari.
Most of the time, it's a matter of a self-atari. In topazg's example, he was probably considering the group connected, and was just thinking on the endgame, not on liberties.

A step above that is missing snapbacks, I think. It happens to me way more than I'd like to admit.

One 1k I played resigned after I killed his invasion despite being 20ish ahead (albeit with invasion potential in his moyo) - that was quite amusing... People will do silly things at all levels - I've witnessed self-atari twice in real life watching dan-level games - one was the game topazg linked below, felt kind of sick seeing him do that! The other game was when the player was doing 20 stones in 5 minutes byo yomi - still a 1d though, so not something you'd expect to see every day.

I self-atarid a big group against Andrew Kay in the British Challengers' Tournament last year, but I was a long way behind anyway so it was more amusing than upsetting, though not as amusing as the dango I made earlier in the game that lived at 1-1.



EDIT: Oh, that wasn't self atari, but almost as bad.

This gives me hope
