Three things are most important for anyone who wants to be successful using Twitter for relationship building:
1. Being available as much as possible.
2. Constantly producing and curating content to attract those who don't know you or may feel reluctant to reach out.
3. Being genuine, authentic and open to conversation.
Yes, it takes commitment. You have to make yourself available for interaction, and you need to have a good content plan for sharing. But if you have a strategy for taking care of both of those, and a little discipline, you'll be successful.
I love the Twitter platform because it's fast, it's easy, and it fits into my busy schedule. I'm a single dad on the go--constantly traveling for business and spending as much time as I can with my two teenage daughters. So I'm always looking for ways to connect and stay connected easily with my personal and professional network... and in a way that scales.
For me Twitter allows so many to not only interact and engage with you but also for the lurkers (who are the vast majority) to do so vicariously through your engagement with others.
Relationships are like muscle tissue; the more they are engaged, the stronger and more valuable they become.
So... welcome to the 'Age of Influence,' where anyone can build an audience and effect change, advocate brands, build relationships at scale... and make a difference in the lives of others.
