We don't provide an alternative. Linkedin has many drawbacks. We provide a solution. The problem is that Linkedin has a huge audience. It will be very difficult to convey information to the entire audience. But I am sure that those who want to study our project will understand that using AskBrains is much more convenient.
But I do not think that Linkedin is a direct competitor. Linkedin offer only professional social network. Project AskBrains is the intended place where partnerships and deals are made.

Each expert will be able to add a user to "favourite list", and then they will be able to communicate like in general social networks (free and without restrictions). Expert can also remove the user from the "favourite list" and user will pay for communication again.
