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.
I'm finding it extremely difficult to find a way to change my career and most advice online is not tailored to this.
A recruiting service for matching skilled, quality people who are looking to change careers with open-minded employers who are willing to consider these non-traditional applicants who may not have the standard background of X years experience in Y would be a good idea.
The value lies in those communties. Creating my own community platform is something I've been noodling for some time. Reddit is terrific, but it's cookie cutter and not exactly feature rich.
But does it really help? I don't think so.
General advices about what to do make them feel good but they don't really understand what it means and how to really use the advice.
I think compared to giving and finding advice, teaching students how to analyze their own career and come up with a practical plan to carry out is more helpful.
Let them write down what they have done and the outcome in different periods, help them prioritize what matters to them and what they want to achieve, then match the best consultant or advice for him. It's like how you mentor a real person in a company.
I think most people here are better than average. The result may be different from what you really need.
For students there is also http://academia.stackexchange.com/ that deals with the immediate problems they face.
