Door to Door Evangelism - Is this an effective method of spreading the Word?

Join the B Word as we discuss this controversial method of spreading the "Word".  Is the door to door method of preaching/teaching effective or do these individuals turn away more individuals than draw them to their belief system.  I will discuss my own experience with these door-to-door pitchmen and offer my own views and opinions on how effective this method of spreading the "Word" is to me.  The B Word welcomes your views and opinions as well!
