A Buddhist I know said that the thing that troubled them about the digital media field was how it conflicted with their great respect for some of the ideas that are central to that philosophy. They said that they identified much modern media consumption as intoxication of the mind with what may amount to trivial experiences tangential to achieving happiness and peace, which they viewed as quite apart from the endless sensory experiences of the world. (For a simple example, they pointed to Youtube)
After some searching, this seems to be the reference: http://www.accesstoinsight.org/ptf/dhamma/sacca/sacca4/samma...
A [lay person] should not engage in five types of business. Which five? Business in weapons, business in human beings, business in meat, business in intoxicants, and business in poison.
Personally my friend's perspective did make me feel a little guilty about my work, since I am also (if sporadically) very interested in Buddhist philosophy and because encouraging people to spend their time "in earnest" (from a Buddhist perspective) is no doubt a personal failure as seen by the Buddhist teachings, in so far as I can grasp them myself. Yet, Buddhism also teaches that we should respect the treasure of conscience as a means to change our ways, and it is certainly true that communications of any kind can certainly be a bringer of good ... as well as thoughtless trivia.
