Haha, thanks! I'm always surprised when a developer doesn't "get" it. Haven't we all been asked to implement FizzBuzz?
I've been a fan of Upwork having tests for freelancers and then publishing their score on their profiles. You should also check out Harj Taggar's company, TripleByte - he was super involved in YC back in the day. (He may still be, but not sure!)
Fizbuz places the developer first, and we want to build tools for developers that help them manage their career and brand over the course of decades. We will work with companies looking to hire as a byproduct of helping developers accomplish a goal (i.e. getting a job).
Doing the right thing for the developer is our #1 principle. Which is why we will never implement anything like InMail.
Do you think you'll eventually start building mentor networks?
