There are ways but the first question back to you is why do you want more followers? Is it an ego thing?
The only thing that more hubber followers does is inflate your ego. There is no monetary gain. There is no guarantee that the followers are following you for the right reasons. They may only wish you to follow them back, just to show that they have a lot of followers. I am not sure but it may have an impact on your hubscore, but that is meaningless also.
To gain more followers:
Write hubs that are entertaining, full of good information and insightful and are relevant to the audience you are aiming at.That way you will get meaningful followers.
Become a part of the community and post answers to questions and delve into the forums and post meaningful remarks in the discussions. These will show those that might like your musings that you exist.
Post comments on hubs that you read from other hubbers - but make them relevant to the hub and not just a meaningless 'great hub' - you can do the latter by just voting up and giving a boost to the hub with 'useful' etc.
Become a fan of other hubbers and give some insight to them as to why you want to be a fan. They may reciprocate - but don't do this just to build your fan club, they will be fickle friends and will likely not read your hubs.
What you really want is for people outside of hubpages to read your articles. It is they that can produce income for you - hubbers cannot as this would infringe the google adsense way of doing things.
If you want to know how to get income from what you do at hubpages then use the search box at the top of your screen and search for 'making money on hubpages' or something similar. You will get a lot of useful pointers.
Most important for all aspects of being at hubpages - write good copy whatever area of hubpages you are on - google is watching!!!
