My point is that even with a comfortable salary, I will feel ~£600/month in energy. I can only fear for people that earn much less than me.
My impression of the readership is that it depends on the time of day. When I was in Vietnam, I would wake up to US centric posts full of comments. When I wake up early on the East Coast of the US (~6:30 am) I see more comments from Europe/UK. By mid afternoon, most of the posters seem to be from the US or at least the Americas.
I base this on about 5 years of daily HN reading. I infer the posters’ locations from spelling, grammar, but most often their own admission. Nonetheless, this is just anecdata.
38F = 3½C
57F = 14C
Not sure why you used Farenheit, but I live in the north too and it's colder and warmer than that. Currently 22C (61F) here in rainy Manchester.
First, I'm not in Manchester, considerably more northern, so why try to compare?
Secondly, Manchester's average temperature in August is close to 16C (https://en.wikipedia.org/wiki/Manchester#Climate).
Thirdly what is strange about the temperature on a given day being higher than the average?
People from Europe likely already have a vague idea of what the temp is like in northern parts of it, and 45% of HN is from US according to https://news.ycombinator.com/item?id=3298905
