This is backwards. Get those first kind of people to follow you and they may retweet your stuff once in a blue moon but it's just noise amongst the rest of their noise. Get a lot of that second group to follow you and those people will GO TO BAT for you. They're real, engaged followers. Your tweets are far more likely to register with them (or even just be seen) and they can just as easily start network effects that reach the big boys anyway. As a whole they're far more valuable than 1000 of the 'real business men'.
