I agree if you comment on something you should follow topic. However I would urge you to consider the people commenting are just trying to figure steemit out and see if they can make a little money. Being new myself it does seem like a slow grind to create any income. The idea is that everyone on steemit should be able to make money and the more they make the more people will want in and drive up value this would cause the "whale" to have the most incentive to make the small fish that are trying to create quality content feel welcome and rewarded.
