Shit country army hydration "pack": half a teaspoon of sugar, half a teaspoon of salt to ~1L of water.
Tastes like shit, but damn it cures hangovers. Also, probably hydrates.

Haven't tried it myself but I've heard that it does not taste like shit.

6 teasponfuls of sugar, 1/2 of salt, 1 liter of water, done.

I just measured mine using a scale and my teaspoon is around 4 ml when filled with water (probably closer to 3 ml when not heaped and no surface tension), my tablespoon around 9 ml, so close enough I guess.
For 1 litre / 1 quart, you'd add about 2 tablespoons (about 30--35g) sugar, and "a pinch" (1--2 g) of salt.

Salt concentrations are tricky too. Saline solution is ~3500mg/L of sodium, but that's over kill for drinking. Since you reabsorb some sodium when you sweat (less if you sweat more), you wouldn't want to replace lost water with an isotonic mixture.
My rationale is that the recipe should be free-standing and not presume other feeding. If that's a consideration, it's not part of the baseline assumptions and formula.
My principle beef with the suggestion I'd replied to is that it has far too much salt, more than I've seen suggested in any other sources I've run across.
If you've specific information that Wikihow is not reliable in this case, I'd be happy to see it.

I think it's reasonable, and necessary, to say that the burden of proof is on the source (i.e. Wikihow); it's not up to others to establish their credibility. Imagine submitting a paper that makes a claim and says only 'prove it wrong'. The Internet is filled with unsubstantiated claims; not only do they do a lot of harm, practically readers don't have time to do the substantiating for them.

In this day and age, we know that 'numerous people' is not evidence of accuracy.
Given that we're contrasting it to Some Guy on Hacker News, of the two, I'd tend to go with the more-reviewed site.
Your quesition is a fair one. I've answered it. But rather than actually confirm or refute the reference cited ... you're engaging in meta arguments. Given the ease of finding confirming or disproving evidence, that's ... kind of tedious.

We're not, afaik. In that and other points, I think you overlooked some parts of my comments or I didn't make them clearly enough, but I'm sure we both have better things to do!
Would 2-3L every day be ok?
Drink if you're thirsty. Drink if your urine is limited or dark for no other apparent cause. (There are both dangerous and benign reasons for coloured urine, including internal bleeding (deep brown, very bad) and excess vitamin B (harmless, bright yellow), again, general guidance is difficult.)
An isotonic solution is most recommended where you're already dehydrated and are trying to re-hydrate rapidly. Under normal circumstances, it's not necessary. Drinking more than a couple of quarts / litres at a time (say, within 10 minutes) is probably excessive, and if you find yourself doing so you may have other problems.
Recommended daily sodium intake is < 2,300 mg, with an "ideal limit" of 1,500 mg/dy, though again this depends very heavily on circumstances.

If you believe what I read on the Intertubes, a person can sweat out nearly 1,500 mg of salt in an hour (1,300 here).

Under most reasonable / normal conditions, we're again at a couple of litres of isotonic solution, though again, this can vary considerably.
Under heavy exercise I can easily drink 2--3 litres of water in a couple of hours, but that's with profuse sweat. I typically don't drink an isotonic solution, though I may mix up some in one of my two bike water bottles, or as an after-workout drink following a gym session.
