What will the fees be like on this platform?
There will not be any fees. They only costs is the price of the ethereum transaction.
Our goal is to reach mass adoption, hence no fees, and in a 2nd stage add premium features for intensive users. Similar approach of what Linkedin did.

Seems like a good plan of action. The ICO should be able to fund the project to get you through to mass adoption too so that you can add the premium features later.
