Getting my groove on with Twitter

I will be the first to say that I am new to the Social Media scene. I am not 24/7 tweeter, nor do I blog scribe. But I do like to think that I have a groove going. I know the lingo, I follow the golden rules to Twitter, and I engage with the big boys (Twitter, WordPress, Facebook, Linkedin).

But there is something that still stumps me. We have been having increasing success with traffic to our company blog, in thanks to some great writers. One would think that the increase in blog traffic would subsequently increase Twitter followers. So why is this not the case? Sure, some readers are becoming followers, but not at the success rate that the blog is getting. What is the differentiator that causes this riff? If readers are enjoying blogs, wouldn’t they be interested to hear what the writer has to say on a daily basis? Is there a formula to success with this?

Any insights would be most helpful. Thanks in advance. @redfelt13
