"Getting the word out" is certainly one of the biggest hurdles we have in any venture we undertake. And doing it CREDIBLY even moreso. After all, we've all encourted charletains of one sort or another who professed certain talent or expertise...but then we discovered (too late, no doubt) that it was all a ruse, that they simply spun a web to get down into our wallet. No one wants that to happen to them!
Frankly, that IS the beauty of Facebook. When you put yourself "out there" personally, you begin to gather your friends and family and share all sorts of things. Some things are consequential...some not so much. Eventually, if you keep active in the platform, you discover that something else you begin to gather is NEW friends. People who are already friends of your "friends", or people who have similar interests as you. It's the perfect place to begin creating that credibiltiy.
But what about the "business" portion of it?
