Clearly the author of this reading hasn't seen a flame war. Some make use of time to maintain their own finesse, but usually when people argue over the internet, rather than think, they opt to just call the other side a bunch of [homophobic slurs]* or something. (Is that appropriate to write in this blog? Can I use that sentence?)
But to be serious, I do not see what the author is trying to explain. Computer programs definitely have us using time a lot differently. However, I do not see how asynchronicity is equivalent to being "against time". Actually, technology seems far less about eliminating the effects of time and more about letting us manage time, rather than letting time manage us. I don't consider that against time, but just different use of time. Ultimately, computers will use time however you use time on them. Those messages you get don't come from a cloud in space, but from other users whose "now" might be different than the "now" when you read them. On a computer, there are things you feel the need to do right away and others that you want to wait on for a long time, but isn't that just like real life? You cannot surrender time to technology. You surrender it to whatever your habits happen to be.
Of course, since we are in a class all about time, it's interesting to read about time's role in digital media. It's a good reminder to think about how we manage time as we do our projects.
