As someone who grew up in "the truth" I remember back in the 1960's and 70's hearing about certain beliefs that early JW's had and I remember how everyone use to chuckle over how cute and quaint the old understandings were.
I remember how was easy it was to dismiss how important those beliefs were to the JW who went ahead of us and who held them as the gospel truth and were ready to die (and did die) defending them. I suspect that when it comes to the year 1914, many young or new ones today couldn't care less about what that date meant to us. I also know that many of those who relied on the significance of those dates and what they meant in terms of them growing old before the end came, are gone now or are close to being gone.
It's human nature to be predominantly concerned about ones own lifetime and saving ones own skin. No one ever predicts the end will come after they've gone, they want to believe it will happen during their lifetime. Each Generation of the Watchtower Leaders made sure to predict that the end would come during their lifetime so they not only wouldn't have to worry about growing old and dying themselves, it ensured that they could string their followers along and keep that the donations they were living on, kept rolling in.
Now because of the accountability of the Internet, they are keeping things more generic and providing a "feel good" religion that tickles the ears of their followers without being too specific about anything lest they get called on the carpet in a few years when once again, nothing happens.
