I like DST, but I recognize that it's there largely for cultural reasons. (It doesn't save much energy.) Summer nights should be light until 9:00pm; that goes back to childhood and just seems "right". (I know that that's an emotional argument with no reasonable backing.) On the other hand, I don't it to be dark at 8:00 in the morning in the dead of winter, so I prefer the reversion to standard time in the winter. Want proof that it's cultural? It starts in March and ends in November. Lightwise, March is the midpoint while November is almost the darkest part of the year-- but not cold yet. DST follows the temperature, not the light. People wouldn't like it if they left work in darkness during the high foliage season of October. Hell, I wouldn't like that. What's really going on, of course, is that DST forces everyone to do everything an hour earlier during the lighter months. In companies that care about presence down to exact minutes (thankfully, those are rare in tech) it becomes socially acceptable to work 8-5 instead of 9-6, because everyone is calling 8:00, 9:00. This prevents all that light in the morning from getting wasted, because people are tricked into getting up earlier than they otherwise would. They think getting up at 6:00 is for old people and gym rats, but that's exactly what they do for 8 months out of the year. People who work the standard workday want: (a) at least an hour and a half of light before they leave for work (typically, 8:30); (b) darkness by one hour before the average bedtime (about 10:45), and (c) as much evening light as possible during the nicest months (April, May; September, October) of the year. DST is the hack that makes that possible. One could argue, on the other hand, that it would be better for people to just adapt to asynchrony in work and social life and thus make it irrelevant whether we call the summer sunset "7:30" or "8:30"... but most people don't have that luxury.
