That takes a certain amount of pre-existing interest plus a certain amount of ability to find something matching that interest. Not much, but some. Now, even the most passive and stupid people - a significant demographic, unfortunately - can basically sit back and let the other crazies come to them. The same filtering/targeting tools that have been such a boon for small businesses advertising their products have also been great for every fringe group that used to rely on old fashioned street-pounding evangelism.
