For myself, Art on the Net has been an awesome experience. It's really like a flower that is blooming in the springtime. One of the most valuable things to have come out of it is my chance to meet so many wonderful artists and see a community come into being where before there was only empty ether.
It's also been a joy to see artists works that I would normally never get to see due to logistics.
In the future I hope to see the art.net domain open to all artists and owned by all artists from around the world.
