I like the idea of achievements in a formal sense because they provide interesting data and also give people a way to roadmap game completion. But I'm really not personally fond of the default behavior of achievements on most platforms you get an icon in the corner of the screen telling you that you've gotten an achievement.
Sometimes you've got this really banal message showing up in the middle of a dramatic scene. Sometimes the achievements message ruin a twist right as it is happening. Fortunately platforms such as Steam let you completely hide notifications, but I imagine a lot of people just leave them on because that's the default.
What about you? Do you dislike the popups (and on console platforms, accompanying sound effects) or do you find them enjoyable? A satisfying notification that you're making progress through the game, or that you've overcome some kind of challenge? For example, solving a complex puzzle might be more enjoyable if the game gives you a nice little notification in the corner with a witty pun or something.
