There are a lot of services that you can pay to use. The problem with social networks (which this is) is that though you are willing to pay, others are not, and social networks are worthless without the 'network' part.
OK. Either this is a missed opportunity to satisfy a market need, or there is no market for that kind of social network.
Also, at this time, the service is zero cost. We are launching so that people might interact with the service and provide the type of feedback you are giving us. Any startup is, in many ways, a giant experiment.
We are looking at many different revenue models. However, we will not go with the traditional model we see today, where "we" are the product. We feel just as strongly about that as you do.
We are confident that better revenue models exist, that can support our service, without spying on our members, selling out their personal information or placing arbitrary monthly fees that are inconsistent with the value provided.
Not to "hate" on LinkedIn, but we are interested to explore other ways to build a marketplace that makes it easy for buyers and sellers to interact.
