While this is a great concept, I am not so sure if this will help freelancers in the long run.
As this service becomes more popular, freelancing subscribers will be hurt from the success. More subscribing freelancers? More competition for leads, and once again the same problem of driving down the wage.
As the website states, the pool of freelancing opportunities are pretty limited. It'll more or less stay around the same. So I feel that this service will have same problem like craigslist, odesk etc, but even worse while paying $40/month or $480/year.
