Digital photography should mean that these early years of the 21st century should be incredibly well recorded. 20 or 30 years ago I used to take photos whenever I could but it wasn't cheap and nowhere near as easy as today. It did have the plus side that I've got hard copy (including negatives) of everything and, because of the cost, most photos were worth having!
But look at the average photo today. Kids tend to fill the screen when they take a shot, usually posing. There's none or very little background. All this info will be lost. Most of the images will not survive. Many that do will have no interest to anybody.
I always used to try to set my family shots into a social history background. Even record shots were of the everyday, rather than the unusual. I also tried to catch atmosphere whenever I could.
At the time I had no idea what I'd do with these shots. But already they are historic. They trigger loads of memories on various Facebook groups and on Panoramio. I'm really glad I took them! And I've got a huge resource for blog posts!
