If you write a lot of good hubs on a topic then the followers will come. You don't have enough articles for someone to know if you would be good to follow. If I follow you because I'm interested in your traveling tips and you never write about traveling again then I'm going to unfollow. But if you have four or five articles about traveling then I can expect you have a lot of knowledge and are likely to write more.
So write some more hubs and then worry about followers. You're better off trying to attract traffic from google because those people are likely to click on the ads that will make you money.
