In fact, drinking water in excessive amounts actually killed 28-year-old Jennifer Strange, who was participating in a radio contest to drink as much water as possible to win a gaming system.
Nitpick: The objective of the contest was not "to drink as much water as possible", it was to see who could last the longest without going to the bathroom (it was called "Hold your wee for a Wii"). The rules did, however, require participants to drink a bottle of water at regular intervals.

This seems to be little more than a rehash of old stories.

Is there actually any scientific evidence that the typical western person is healthier when they drink more water? A quick google search didn't hit much (after ignoring the wacko sites) A WebMD page that doesn't actually say more water is better, only that water is important for the body, which isn't the same as saying the typical person needs to ingest more water and will be healthier if they do so.

The Mayo says basically that you need enough water to not feel thirsty.

I don't see anything that says drinking more water than what is needed to not feel thirsty has any health benefits. Does anyone know of anything?

I'm sure at least some of that is when people say "You should drink more water (instead of soda/coffee/etc)", and their audience hears "You should drink more water (as in large amounts, even if you're not thirsty)", and the idea just gets spread around from there.

That and a lot of people still believe that you have to drink at least 8 glasses of water per day, no matter what. I know there's no medical basis for it and snopes has debunked it, but it's still "advice we hear over and over again".

AFA hydration goes, coffee, tea, and soda work just fine. Caffeine may be a diuretic but it is a very mild one, not enough to offset the hydrating effect of the water. AFAIK, the only thing we drink that has a net dehydrating effect is hard liquor, from the alcohol.

True. But not just hard liquor.

Beer does a double whammy on you. It has the alcohol, which is a good diuretic. It also has something (from the hops, I believe) that is known as an "anti-diuretic hormone inhibitor" which blocks your body's restraint on producing urine. So, you get something to make you pee, and you lose the limits on producing pee. So, you pee a lot.

From a year of human anatomy and physiology at university, this is about all I can recall from the time spent on the kidneys.

I'm not sure I understand your reply; I wasn't talking about hydration, but misinterpretation.

I mean when person A says, "Drink lots of water" (instead of Coke, because Coke has lots of calories). Or "Drink lots of water" (instead of fruit juice, because those sometimes have too much sugar/acid/etc). But person B interprets it as "Drink lots of water" (even if you're not thirsty, because overhydrating flushes out your system or whatever).

I'm not personally taking a stance on what liquids are more hydrating, or even which drinks have too many calories/sugars/acids. I'm just explaining how a specific sentence can be misinterpreted.

Just as relying on food urges can lead to a bad diet, relying exclusively on thirst for sating same can be a problem. Some conditions - diseases, medications, mental state, etc. - can make a person desire more or less of something than what is healthy. For hydration, it is good to be aware of your total intake from ALL sources, as well as unique demands (like working out or being in sun or wind), and inquire if thirst or lack thereof is is substantially out of whack with actual hydration status. For instance, if you get plenty of liquids, but you are constantly thirsty, that is one of the major warning signs of diabetes.
