I'll say it. I <3 daylight savings time and everything about it.
I'm a bit undecided on its effects on winter. We could do like Russia and make it "all DST, all the time" and get sun late into the evening every day. But that would eventually just shift our concept of time, and everyone would go to work later and everything would open later, and we'd be back to wasting our summer mornings.
But no, DST doesn't make sense for everyone. Particularly if you are close to the equator, or in the opposite case, so far away from it that your solar hours weren't that useful to begin with.
Also, no, DST is not an energy saving scheme anymore. That's an easy straw man to knock down, so go ahead and knock it down if you wish :-) The commercial and cultural aspect is important. 9pm summer sun is something many of us would go crazy without.
