The site is going to be a social media site, potentially called ThoughtLeader.com, (subject to change).
The purpose of the site is to share knowledge you have in topics you are knowledgeable in, and subscribe to the knowledge of others.
When you create a profile and are filling in your personal information, you also select your areas of expertise, such as marketing, sales, biology, whatever you are knowledgeable in. These topics will be displayed on your profile.
When you post a status updates (called a "thought"), you select what topic of your expertise it is about, and you basically write a piece of advice, or a tip, on that topic (i.e. a marketing tip for example).
Instead of having "friends" or "followers," you have "Students" who follow you as a Thought Leader. They basically subscribe to the advice you are posting. This is done with the "Become a Student" button.
