Clearly define what your aim is (not "grow the twitter followers by 50%") in a business context. "I am going to build a relationship with 50 bloggers pertinent to our product"

Your community is likely to be very nascent, and so you'll need to complete grok the space your in, really take the time to understand what the "continual conversations" are between the community (there's always one. Think Python vs Ruby on HN)make sure you understand it, the key players who takes which view...

Once you've fully groked the environment, use being the "twiter dude" as a way to meet people for coffee's and beers, then scale to being a biz dev.

Simples.

Remember, you there to make money not have a natter. :)
