I agree with what @meesterboom wrote: you will get a few decent people.. and a lot of reward farmers. But among these last ones, some - with time - might become good followers. If more people start to read your posts and reflect about what you wrote, I believe a few will realize that they actually like your style and your writings, so they will slowly turn into real followers who post meaningful comments not for the rewards, but because they enjoy it.

It will require time and, at the beginning, patience, but in the long run it might give you good result!
