not to be mean, but why would you want to?
when you write hubs, and if you do everything right, you can expect 2 waves of traffic.
the first will be people who follow the category you write about, plus your followers. generally speaking this first wave of traffic (the spike) doesn't do much with your content.
because they are using hubpages the same way you are, most likely. they will not click on ads, nor will they do much with your content.
now, depending upon the type of article you wrote and what your keywords are your article will climb the google ladder. when this happens you will get traffic to your hubs through search engines, and this is the traffic you want b/c when they read your stuff, provided it's good content, they will do something, take action.
so, worry less about getting followers and instead focus on writing good content that targets a good keyword.
