I don't think the issue is about "ignorance." Mastering the Internet is not the equivalent of wisdom any more than buying thirty books on the French language means one is fluent in French.
The amount of information one possesses is not directly related to the ability one has of leading. By analogy a sniper's expertise is not determined by how many bullets the magazine in his gun holds.
I'd bet that there are very few significant events that McCain does not know about. Also, I don't know if you have ever flown in a fighter plane (I have not), but you have to master a significant amount of information to stay in the air. Annapolis is a very difficult University to get through.
As the article points out, Tony Blair did not have a cell phone the entire time he was leading (and doing so effectively) a major world power.
I wouldn't make too much of McCain's lack of interest in My Space.
