I answer a lot of question on Quora & Reddit about CS career stuff, I think it's nice to have a community, but reddit questions are more natural and less for show.

Quora career advice stuff have so much artificial taste added to it, such as: recruiter adding very weird advice and getting upvotes. While the answer would still not get a proper answer.

There is actually a startup called Career Dean, that is their whole mission.
