Well good you asked the question but for someone to gain influence on POB community or Hive ecosystem at large requires a lot and it will first cost you in someways which may differ.

First is that you have to have enough staking power to be able to vote and bestow some reasonable amount of POB token with your vote only.
Having staking power makes people want to follow you and comment on your posts or reply your comments so that you will be able to vote them.

Another thing that will make others follow you is the reason that you always write quality and reasonable post that in the platform. Which is a least drop one comment in a day or two for people to be able to read through and drop there comments on your post.

Dropping this post and getting people to comment is a secret tip to hold them to follow you because whenever you post and they comment on your post try as much as possible to vote those that commented on you post this will make them to keep track on you always.

In all that too you also have to be engaging in Posts in the community to make yourself know by other participants.

Well I hope the little point of mine helps to answer your question.
