I think the internet provides something that the congregation doesn't and can't and that is a sense of connectedness. Connectedness to the wider world and the local community.
WT can't compete, their website is not interactive, they don't give a fuck what you think or feel where as you can always find someplace or someone on the internet to relate to. Even casual interactions on the internet are more satifying than real world interactions with the shallow brothers and sisters at the fake-ass KH or with cold would-kick-you-to-the-curb-in-a-heartbeat fake-ass, conditional JW family.
