Does art require an explanation?
Now, I don’t expect you to explain your every idea in great detail, however, if you give me a hint or two, just a little background or explanation the likelihood I will be engaged and interested enough to take a closer look and form my own opinion is much greater. I think this is probably even important for internet artworks since when I go to a gallery I already have a set of expectations, I have a place of reference and a framework to start with. Most people who enter a gallery will get there through the front door. With internet art people arrive from many different directions and they are seeking and expecting many different things. Of course the fact that people are expecting a certain thing within the internet is a good opportunity to play with those perceptions, and to use those perceptions against the reader in a judo-esque manner, yet I think that opportunity is often lost as it is as easy to leave a site as it is to stumble across one.
