We must base ourselves on statistics, in marketing only 3% of the people you manage to reach stay or are interested, of that% only 3% will be valuable users for the community, it is a rule of 3 widely used in marketing. It would be a question of getting numbers, because if 5 thousand people are reached, 3% of all that prospecting does not seem bad for the community! In 3speak I was looking at a guy who had the intention of doing something related to marketing for Hive then I stopped following what he was doing, it would be a matter of taking a look and taking the good of that to duplicate it!
