Good idea, but I don't see the point.
I got a virtual advisor when I was an M4, and although she was both friendly and knowledgable, she wasn't able to help very much.
Most of my M4 questions were the same as everyone else's:
What are my chances?
What do you think about this program?
What should I look for in a residency?
Why haven't I gotten more interview invites?
Search the archives here for these answers.
A real advisor is someone you connect with on a visceral level, who serves as a mentor and guide. Also someone with connections who can hook you up with the right people you need.
BTW, you have at least five virtual advisors here on Scutwork. DocB's a veteran in private practice. Rumor has it he's even living the dream of the democratic group. Quinn, myself and Roja are all new attendings in academics. BKN is a PD. What more could you want?
