Thanks and great you share the pain. Critical mass of users We are trying to use linkedin :). We are researching the most active set of users on linkedin (apart from sales and recruiters) and thinking to cater to one vertical to start with so maybe engineers and technology people or new graduate students Fighting linkedin - Agreed. Its a gigantic company and a very difficult fight with amazing engineering talent. Convincing users to open another professional site account is not our value proposition, instead creating a product where they find a value proposition different from Linkedin's is where we want to concentrate. Also, YC's and HN's guidance can help here. Please share if you have any ideas too on your second question
