Maybe I'm unique, but I would never apply for a job if I didn't know where I was applying. I want to know a lot about the company before I even consider taking the time to apply for the job. Why waste my time only to find out my supposed dream job is actually located somewhere I'd never want to move or with a company that I'd never want to work for?
The blog post about this service talks a lot about how important finding the right "fit" between employee and employer is ... but if the applicants never even know what or where or who they're applying to, doesn't that just add an extra step in trying to determine if there is a fit?
I understand the idea of making it easier to tweet out job links and spread job listing virally. Not a bad idea. But not sure I understand how this many any more sense than just using bit.ly to link to a traditional, full job listing somewhere else.
