the deep structure of the text/algorithm interaction inherent in all digital textuality — those places where the mathematical underpinnings of text as it appears on the screen (since there is always something at work keeping the text you are reading now visible) and how artists exploit them to create unique effects
I find this, as well as the whole concept of a simple, to be much more precise a way of defining electronic literature through its own nature and not through the concept of literary arts and its translations. As many electronic literature artists are not necessarily good traditional writers, it seems that the definition of the field should focus more on the technological underpinnings of the practices rather than their relations to literary arts. This depiction of artists exploiting and pushing the envelope of text/algorithm interaction captures this aspect quite well.
