It is not that important to have hundreds or thousands of followers. You may get an increase in traffic and it certainly feels good to have people following you. Yet, think about your writing goals. If you write just for the fun of it, then yes, you should get as many followers as you can. But, if your goal is also to make money, SEO is king and followers are little pawns. I am not implying they are irrelevant, but I claim that they are not the most important element in terms of making money. Take a better look at the profile of the hubber Five One Cows. The hubber has more than a thousand followers, but the hub has been read only over a 1000 times - which is nothing if we are talking in terms of money (check the accolades on the profile).
You will get followers if you write such quality content that people actually learn from you! They want the information that corresponds to their personal needs. I myself have not really gotten there, but I concluded this following the success of other hubbers. My favorite: Susana S (I recommend you check out her profile).
