hey! well i wouldnt say it is necessary no.. It all depends on your own style.. If you are more technically inclined then you can get some good help by using some of the systems on streemian and other ideas.. but you can do equally well or even better if you post the right kind of content..

I think the bottom line is you have to just be consistent and write and comment well.. then over time you will do well.. it does take time though.. i dont think thre are any shortcuts to that other than piling in a LOT of money.

my best advice is to focus on getting followers. The best way to do that is to comment really well and thoughtfully on many popular and new posts.. Without many followers it is very hard to succeed.

I hope that helps!
BEst of luck!
