I would like to ask you for your opinion on pros and cons of 2 different business models for a social networking+user advertising start up.
For a very vague description and comparison, imagine this project is somewhat similar to linkedin. Project target market is business sector.
Which of the two do you think its better business model:
a) Have the website completely free for everybody and base the revenue on advertising?
b) Offer some of the features free, however limited and base the revenue on paid subscriptions which user needs to pay in order to get access to the premium content and "full usability".
Which of the two models do you think offers bigger opportunity for growth? Or do you perhaps have any other suggestion that might work?
Thank you very much for you opinion on the subject. It is much appreciated.
