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.
For me, linkedin is generally a separate social network and our project cannot compete with it, since it is completely fresh in the market.
