After thinking about what people actually WANT, I figured they wouldn't want to wade through thousands (more?) job descriptions. Don't tell me what's out there, just tell me what I would be good at and would like.
So I started to think about a tool that would categorize available jobs based on what people REALLY look for in a job. Users could identify what they (thought) they wanted and the tool would show them jobs that fit.
After many months I was losing interest. Then I recently discovered Aaron Swartz was working on something similar. "...we did agree on another good idea: a wiki to tell students what different jobs are like. That site should be launching soon."[1]
I'm not sure how far Aaron got with the project, but I think the idea is still viable. I often find myself doing a lot of research and job description comparisons to get past the cookie cutter information to attempt to answer the question, "what exactly will I be doing for you?"
Maybe I'm alone, but the majority of job interviews I've had were more about seeking information about the work I was going to be doing. Information I should have had well before I ever applied.
