if actually interested, the article does mention where one such difference is found.
To be honest, I didn't even know biblical textual scholars existed, let alone what they did with their time. Now I know: http://en.wikipedia.org/wiki/Textual_criticism .
Its closer to the truth to call the Bible a scrap-book of letters, personal accounts, advice for living, poetry, religious writings, and history spanning many centuries.
Those that have believed it have carefully assembled it over the millennia (yeah, some of it is that old!) in order to tell the story of God's relation to man.
Emptied of its religious context, (and sadly, modern connotative baggage that is has accumulated in the last few centuries), it is one of the most fascinating artifacts of ancient humans to be found anywhere. Its ubiquity belies the fact that it is well worth study in this regard.
