Absolutely. What I'd like to see is for a person to say "hey, I want to become an Information Security Analyst" and start tracking their progress, while at the same time mentors can say "hey, I'm happy to teach people about ISA" and the system connects the two. This could then be an easy hook in for recruiters looking to employ ISA folks.
I'd just like to highlight that to me there are two sides to the "education" coin:
(1) What you want to learn for yourself
(2) What "proves" to others your are educated or skilled in a particular vein and thus become employed
So for me the angle of what I want to learn is nice, but at the end of the day it is my ability to convince others to hire me for work which requires such education is the main challenge. By example, I am currently career track splitting and developing my skill set as an Information Security Analyst. I've been learning how to use Wireshark, a popular tool, and the intricacies of network packet analysis. Despite all the self education I am doing, the various job opportunities out there only care if I have certifications (GIAC, CISSP, etc). So it doesn't really matter what I learn on my own unless I use that to gain certification somewhere else.
The rub for me personally is that all of these organizations charge big money up front to take the test, and then usually a maintenance fee of some sort - just to say I am certified! So what I would like WhatYouKnow.com to become is a place where an employer could go and have reasonable confidence in my rating to give me a job and let me start proving myself without the "pay to play" mentality.
