Service targetting for those who are 35 or over

I guess the construction of the "Matrix" by age division is beggining to materialize. Get Back Media Co. from the U.S. began the new SNS targetting users who are 35 or over from 23rd this month.

SNS now is more likely for those who are under, say around 30 or so. Students are the main players in SNS world. Since we started to use the internet, applications which are not designed for business are only used among young users. I wonder how will the people who use internet as just for business affect Social graph. From the advitisers point of view, business users are obviously welcomed at any cost. Yet how will they gain merit in commiting in Social graph?? There are so many aspects that must be comsidered...
