Well instead of job titles, have it based on other parameters. Example: Degree, College graduated from, years in field, field, area

Then you can do all sorts of fancy stuff (income vs. location; true after-tax income; ratio of income vs. COLA)

Then you could monetize it quickly by linking to off-site job postings, creating your own job board, offering banking opportunities.

yep, gonna file that one away in my idea book.
