> The mean Facebook user doesn't care about latency.
They do, they just don't know it, yet. If you showed them two versions of Facebook, one which was their normal latent mess, and one which had half the latency, they'll take the less-latent version every single time.
Don't assume that people don't care - they definitely do, they just don't have a choice.
Plus it's not like they are just handed out and you're on your own. A nice man or woman in a suit will spend many hours sitting beside you teaching you everything you want to know. And anytime you are confused you press the help key twice and you are connected with someone who will take you through step by step what to do. And this isn't outsourced IT support. It's a person in New York who knows the product really well.
