"Showing people online" doesn't appeal to me quite as much as it would some others because I don't play games in the hopes that someone will pat me on the back for sitting around with a piece of plastic in my hand. They don't absolutely torture me, but they do pop around with their cute little sound at inconvenient times and thus manage to break any flow or immersion that might have existed at the time.

Exactly! I couldn't be in more agreement with this guy. Nothing destroys my enjoyment and immersion in a game quite as much as that God damn "bleep" sound as that stupid message pops up. I see no reason why there isn't a feature that would allow you to disable that pop-up without disabling other notices.
That said, I honestly do feel that achievements have ruined many games and have "corrupted" gamers in general. I know far too many gamers that play a game simply to get it's achievements. Then, having beaten the game or, more likely, having unlocked around half of the achievements, turn around and sell the game never bothering to experience it in full. This is why so many garbage, ill-designed games are selling as well as or even better than the few true, top tier quality titles. Achievements are an excuse for many developers to skimp on content by just adding these pointless challenges.
That said, there are a few exceptions. Every once in a while a game designer throws a few achievements in their game that are witty, quirky, and unique. (besides the usual kill X bad guys with weapon Y. play for X hours. complete chapter. etc.) Valve seems to have fun with their achievements in the Orange Box and L4D. As did Real Time Worlds in Crackdown.
