I think the first line of the article sends up red flags: "I really like Nicolas Cage as an actor."
I kid! I kid!
This article seems to be espousing a view of the book of Revelation known as "full preterism" which is rather problematic. It's hard to say whether or not the author himself denies that Jesus will come again... many full preterists, though, do deny it. Some don't. But their main thrust is that everything in the book of Revelation happened in the near-future from when Revelation was written. (Within a generation). This doesn't necessarily say anything about their end-times theology... just how they interpret the entire book.
I think we need to have doctrinal humility when talking about eschatology, though. (Remember how Saul of Tarsus knew the Hebrew Bible in its entirety and understood about biblical prophecy? What conclusions did he draw? That's right... his Bible knowledge led him to the belief that "Jesus in not the Messiah and I should kill his followers")
Also we need to separate two issues:
1. Eschatology (End Times Studies), which draws conclusions about the end times from ALL the biblical data
2. Interpretation of Revelation, which is only concerned with how Revelation's data is interpreted. (Yes it will have an effect on a person's eschatology, but end-times data is found throughout the Bible, not just in Revelation).
So... anyhow... partial preterism is a pretty viable viewpoint (that is, some of Revelation has been fulfilled) but that last chapter is hard to imagine having taken place already.
Just for the record I'm a progressive dispensationalist... so I'd disagree with some of the Left Behind theology. But I think the LEft Behind theology can make a good argument from the text.
