You may be generally right but you don’t speak for me! ;)

I read this and sincerely thought “wow, I haven’t ever given much thought to the intricacies of twilight but it’s really interesting!” Then again it’s around this time of year I start to regularly visit the site posting this article, and I’m not so much concerned with making more friends.

In my experience people think it's helpful sometimes, because they know that sunset doesn't mean the light suddenly disappears, but don't know how to act on that more predictably. So if you're doing something with people outdoors around twilight, and people are wondering exactly how much light there will be at different times, bringing it up is a good thing.

install the 'suntimes' app from fdroid and never get bored telling people which sunset is when, or what time it really is

moon stuff too! it's gibbous you know

Tiffany knew it was gibbous because she’d read in the Almanack that gibbous meant what the moon looked like when it was just a bit fatter than half full, and so she made a point of paying attention to it around those times just so that she could say to herself: “Ah, I see the moon’s very gibbous tonight . . .”

It’s possible that this tells you more about Tiffany than she would want you to know.
