While I agree with you to a large extent, I think you can't be too quick to dismiss the fact that sometimes people will just have completely different standards than you. Sometimes it's not malice so much as people's notions of what's good have evolved a bit, for better or for worse.
I wouldn't EVER deliberately stall, and I would never resign in a DT, but I literally resign in ELO
each time a game is obviously (or even probably) lost. I personally feel that most ELO
players come into the room to try to work on their ELO
score, and I feel that resigning gives them more time to do so. It also strikes me as a polite way to acknowledge your respect for your opponent's skill.
It never occurred to me that it might be frustrating to someone in ELO
that I've resigned... My personal preference is not to waste time sitting in a game I've won -- I'd rather my opponent quit, and if I need that extra KO, I can go play many quick, reckless games in DT.
I'm considerably younger than you, though still quite old by UR standards. My observation is that computers have increased desire for efficiency in people. I think ELO
resignations are an example of that. In some cases, it's easy to mistake someone innocently trying to do things in a different way for disrespect. Just some food for thought.
