I’m cynically viewing this as not a positive. I assume this is so they can make pages 2, 3 and so on as spammy as page 1.
Not at first, obviously. You don’t boil that frog on high heat.
You throw out a second page with a cute little text ad off to the side, then 1 or 2 at the top, then a mid-page ad. Maybe some suggested content.
Instead of having to scroll through a page’s worth of ads to get to semi-relevant results with a gem hidden in them, it’ll be a pages worth of ads for your semi-relevant results per page, and maybe what you were looking for 4 or 5 pages in.
Google used to be good. They ‘know’ what people are looking for. So they’ll probably hire someone familiar with gambling to figure out a minimum dispersion of relevant results on the pages, to keep people using the service and scrolling past ads. … I used to remember this. Variable-ratio reward schedule?
There’s a difference between summer and winter fuel for gasoline engines in some areas. It’s usually to do with smog restrictions.
The same octane can be reached with different blends of hydrocarbons. So instead of just ‘pure’ gasoline to hit a desired octane, refineries can mix together higher and lower octane fuels to reach the same overall octane rating. This increases the amount of refinery products that can be used to blend gasoline, so it can be made more cheaply. The trade off is that it’s less pure, and most importantly for this comment - that some components of of these cheaper blends may evaporate more readily, leading to smog.
In summer, when it’s warmer, some areas mandate gasoline must meet certain standards for evaporation. In winter, those standards are decreased, because it’s cooler.
Ethanol has a relatively low evaporation point. I don’t know the specifics of the commenter’s location, but I could see ‘summer gas’ having no ethanol to meet these standards.
