I agree with those who predict a generational transition affecting the WTBTS. (boy, I think the GB is going to end up hating the word "generation" soon)
For every year that passes in the information age, more and more, people in the West esp are going to view suspiciously any person or group that tries to demonize the internet. Too much work is done, too much of our economy is tied on the ability to get on the internet. It is in school. Hell, emails rule, IM's rule.
So every generation (there's that word again) from here on out will be less and less inclined to believe what the GB says about the internet. There is a group that is current and that the GB has in its control that they probably don't worry about too much.
Where the internet and Social Networking is going to hurt is in future growth prospects. We are already seeing evidence of that with their move from Brooklyn to rural NY State, and the fact that 3rd world countries are growing at a far greater rate, while Western countries, even Japan, are regressing, exactly because they go online and see the lies.
The fact is, that when a believing JW dares go online to see what is said about JW's, and they see us "apostates", they know that it is true. And they aren't peeking on the internet just for the hell of it. They know something just isn't right about what is going on, and they can sniff the paranoia of the GB, and they want to know why they can't see what others are saying about JW's.
