While they have tried to change to doing business territory and street witnessing, instead of pure door-to-door, my opinion is that there is not a whole lot of reaction to the message in the U.S. except among foreign languages. They are pushing JWs to join those.
The bulk of preaching is to keep rank and file busy SERVING God the Borg. I see them cutting back on what we leave with householders to keep costs down. There was a single sheet invitation to the conventions, now a flyer, Kingdom News Number 37. They want us to make return visits on these folks and they are having us keep count of the flyers, first time for that.
If they asked for more evening preaching, more people would tell them NO, and you can't have people deciding for themselves.
