gweedo, with your logic we would still using brick sized phones since obviously building off of an idea that already exists is "doomed to fail from the beginning". I like the idea of this site and I am looking forward to seeing it.
So I will get pass the fact you are a newbie and this is your first post and say we are talking about two different things. See your talking about taking a product or site and pivoting it to a different thing. They are just taking the original model and doing the same thing.
