According to Lee Blaylock, founder and CEO of new business networking site WhoDoYouKnowAt, many business executives are reluctant to share their contact information publicly. For this reason, a number of professionals are hesitant to network through sites like LinkedIn where you have to connect with your colleagues and then make those connections available to anyone wanting to use your connections for an introduction. WhoDoYouKnowAt flips this concept of business networking on its head, letting you control the level of access to your contacts based on who's asking.
