I believe that any type of curation is still not the answer. The issue has always been passive candidates. How can you expose an opportunity to someone that is not looking? DA does not solve this problem. The only problem that it solves is negotiating salary. You are still dealing with active candidates, candidates that would have found about the companies without going through a recruiter.
I have thought about the recruiting business a lot in the past couple of years. I have a few ideas, but I do not have the time to implement them. They are not trivial and I am content with my day job.
