If your problem is that your working day is too early or too late in the day, maybe thats what should be changed - not everybody's clocks.
Anyway, despite my early schedule, I STILL find that this only buys me barely an hour of daylight in the winter when I get home. Staying on DST year-round would give me an extra hour of time to play outside with the kids, go for a family walk, etc. in the winter months. Selfishly, I'd love it.
And I say selfishly, but I don't think it's entirely selfish. It's not like I'm the only person in this boat. As another commenter pointed out, most social activities tend to happen after work/school in the evenings. I'm imagining the majority of people having more time for outside socializing, exercising, etc. if you just started the school/work day in a couple of hours of darkness and then let them have the sunlight after it was over...
Midday should be the hour when the sun is highest in your timezone, and should stay there all year round.
For people who live on fixed schedules (AKA large swaths of society), changing the clock is how you campaign for schools/work/recreational organizations to start earlier. It is vastly more effective than solving the huge coordination problem of trying to get these independent organizations to each separately change their interlocking schedules.
On the flipside, it (1) seems vaguely annoying to a minority of people who have more flexibility in their schedules and don't need this (but that same flexibility should insulate them from any negative effects) and (2) has some random and irrelevant effect on the location of the sun in the sky at different clock times.
This is irrelevant, as I'd like to have more chance to enjoy the sunset in a park in a company, not just by myself. I also would like my children to have at least an hour of the sun light after school, not before, when it absolutely doesn't matter as they are still groggy and can't really enjoy it. What I was trying to convey in my other comments, this is not strictly a personal issue.
