In the old days (pre-Internet) witnessing was like gunslinging where you stood at the door and shot it out and watched the unindoctrinated bodies fall in a crumpled heap on the doorsill.
Post-internet, however, a conversation with another human being is likely to be more of a death trap for the JW because Ex-JW's have wallpapered with FACTS every search engine pitstop there is.
This is exactly my thinking. Going to someones door with a message is something I can easily see appeal to a person especially when he or she is convinced of the message... like you are easily the only religion around that really does that on a large scale. Standing still on a street with a cart and watch people walk by... you can just look around and next to you there is the hara krishna, the newspaper salesguy, the greenpeace or the other people who flag down people in the street and they are likely doing a much more active job than you.
