You'd have to be one hell of an idiot to air your grievances about being rejected for a job application on a public forum like this. Great way to reduce your job prospects for the future.

I suspect this sort of thing would be fairly rare, because it looks bad on both the applicant and the company.

I don't know if the offer really was insultingly low or not, or if he/she interviewed poorly, or if he/she is highly skilled or not, or whatever. These facts aren't terribly important.

Having a feedback mechanism might encourage people to be nice, and I can't see how that's bad. Yeah it might suck to have to spend an extra two minutes talking to every candidate, but I don't see that making or breaking a company.
