Point well noted about Skype, Kevin. I believe that is a neglected tool as far as relationship building is concerned.

It's surprising how many people will be willing to touch base on Skype even if they are not willing get on the phone with you.

Amazing relationships are built pretty fast on twitter. But you have to work it diligently. Become a part of the conversation. Find what the people you want to connect with are tweeting about and become a part of that conversation. I know people who have built their businesses in the past two years solely through relationships built on twitter. However, not everybody has the discipline and commitment needed to work this fast moving medium. Some people are just naturals and thrive in it.
