I am certainly biased, but I built a job platform because I felt all the existing job boards were lacking, called Limbo.
The long and short of the problem is that great folks are often employed and finding your next ideal role is too time consuming and emotionally taxing, and that great folks with diverse backgrounds are unfairly discriminated against at resume review time. Limbo attempts to solve those problems with an anonymous job platform.
