no you still missing his point. people were convinced to created their profile because other users were already in the network. your idea does not solve chicken-egg problem. I will not sign up for profile or download your software UNLESS you have a database of couple thousands men/women to go through. Unless you have a 25,000 single friends that you can eblast and beg to fill out the form or pay each a dollar for their time, you will fail. it wont matter whether it is profile registration or software download the value is in network.
