Well put.. people will soon realize that even if they do get some response in the beginning - they will never be able to sustain it. Rewards shouldn't be "expected"- especially if you havent built a following. It takes a lot of posts, a few good relationships, and interesting content to build your base. I say participate in other peoples content - and maybe they'll take an interest in yours. It has to be an organic process - it can't be forced!
