Can you help me find a slightly older person a job?

I am in an argument with a Fluther user, who is of a slightly older generation.

This person happens to be job hunting. I have this suggested this person join Linkedin, if only to suggest to possible hiring managers that this person has a network of people who are willing to vouch for them as a professional.

This person thinks I am crazy and that I would be exposing them to the same kind of scrutiny as a facebook page.

Please help me settle this. Am I giving bad advice?
