Barefootsies, my buddy
you left out the part about getting traffic
you have content, product, idea for a paysite, get billing etc but even then you have to get traffic somehow
so after you've done all that you have a great paysite, but with no traffic
you're in same position as some affiliate who starts out
he probably will try to get traffic with the same methods you'll get it
you have an advantage cause you have fresh unsatuyrated content and you're in control of everything, his advantage is that he didnt invest anything yet and he has hundreds of sponsors to chose from, who will supply him with free content ot even hosting
im just saying that its not that you build it and they will come... even if its a very good product
