Change is what the org does. I'm always rather suprised at the excitement on here. the IBSA/WTBTS has continually mutated in belief and structure just as most religions have. Their own book (can't recall the name of it) charts it. So it's not a sign of the end of the religion, just them adapting to the times/technology/economy.
I've always been suprised that the district conventions have continued when they could make model talks with good speakers and pop them on a dvd to be watched at circuit sized events. the districts are a nightmare logistically and unneccessary expense.
