Very good tactic that is exactly how I started myself with commenting and upvoting :-)Think about to integrate resteeming for very good articles or if you want to support someone. Dont be shy and comment with " resteemed ". That will give you later an extra booster when you start with your own articles ;-) Ah and for building followers it is good to mention " you have a new follower " many will follow in return or check your blog at least.
