There is a thread on jwtalk suggesting that the latest hall designs do not feature a literature desk. The dubs will pick up gear from a self serve kiosk in the hall, just enough for their immediate needs.
Time will tell if this is true but if so then it reflects the reducing emphasis on printed material. Also, I think there is another by product. You don't need two or three literature servants. One brother fills the kiosk when it needs refilling and that's it. We all know how the congregations are suffering from a lack of desire to reach out. I am not saying this the is thinking but anything that means you need less willing volunteers...
