Yes the follow for follow strategy is also somewhat troublesome. But it seems appropriate when someone does follow you, to follow back. At least to some extent.
An argument can be made, saying that the people that publish the most often are the people that will be noticed the most.
What I dislike more is when people like or comment on your article just for the sake of getting followers and not exactly really addressing what is mentioned in the article.
That is why when I see a comment that is a personal story, or heartfelt, or a concern for some issue, I truly appreciate it.
Thanks for the comment!
