What I like about Flickr are all the 3rd party mashups and services that people are creating. How neat! I created a Warhol-like mosaic of my son on Warholizer and a six sided cube of my favorite pictures on another "toy" offered by a third party site. Most of them offer the basic service for free, and you can get enhanced services for a fee. The amount of things you can do on your own with pictures is completely amazing. I remember being on the yearbook staff in high school, and we had to work very hard to accomplish special effects. We had to take hundreds of photos to get a "good one," and we wouldn't discover that it was good until a week after we took it because we had to get it developed or develop it ourselves! Digital cameras have really changed photography in a major way.
When I was growing up, I always wondered what would be the big invention of my lifetime. For my grandparents it was transportation and for my great-grandparents it was electricity. I truly believe that computer, digital, wireless (etc.) technology will be mine. In the last 10-15 years, we have been inundated by the amount of information at our fingertips. We can communicate messages, photos, and videos in an instant...and I LOVE it. I love teaching our students about it, and I love learning about it from them.
