It is the London opening. People like to hate it.

Yes, kind of, specific proteins (eg casein) in the milk react with rennet (or acid) and coagulate. That leaves other proteins (eg lactoglobulin) in a water solution that we call whey. It isn't that the rennet or acid is used up, it is that the proteins that will coagulate under those conditions have all coagulated and separated from the whey.
Sorry, I have to do it - Whey is the part of milk that is (mostly) not in cheese. It is the byproduct of cheese making.
It is functioning as mulch. Lets water in but slows evaporation. Allows air transfer to soil but blocks direct sunlight (to keep the actual soil cooler and help prevent weed establishment). Also usually light color stone is used. That will reflect some heat away during the day.
Background soil levels are almost for sure above their lower threshold. Source control is the only way to stop the accumulation.
Definitely the greener option.

Roundup is a systemic herbicide. You have a chance of killing the parent plant since they share roots. It probably won't, but it seems pretty drastic when you could just pull any shoots. You can even pot them up and give them to friends.
I think the best bet would be following recipes. That means finding recipes that minimize 'to taste' instructions. A lot can be done by look and texture, so you can be decent enough for anyone who's not a snob. Also, err on the side of too little salt and put some on the table.
It is the same as other easily spreading plants. In their native habitats there are checks like diseases and predators. When you move them out of those habitats they can thrive at a new level because of the lack of those things.
Beautiful, and an old friend of mine would smile if I tell you that that flower shape is called a scorpiod cyme (pronounced sime) by botanist types.
It is common, some chess celebs don't like it, but not because it is bad strategy.
