all i can say is that it takes time and you have to be consistant in the amount you post. people will start to clue in eventually. you wont get much listens/views off 500 friends. the most you expand your online social circle the more the numbers will flow in. to put it in perspective 1-5% of all the people you have on facebook will view your stuff, roughly. a personal example is my learning journal on Digital DJ Tips forums. at first i didint think anyone would knotice it but just under a year of my posting stuff in it, it almost 3,000 views and on avarage 30-40 people will read a single post right after i write it. Same goes for my Ustream I barely get any views on it but slowly it builds up because I promote the poop out of it. Tricky part is not to get annoying with promoting. I hope this helps.
