Sorry to be unhelpful. The specific examples I could have given you wouldn't have been useful in your personal job search and giving them would have meant betraying the confidence of close friends and acquaintances. My post's somewhat abstract answer was a common denominator.

How many of these can there be if giving any hint to the observable characteristics of any of them will compromise an individual's privacy?

You were hoping for a list of companies where psykotic has friends who have shared their confidential salaries with him/her, usually small web businesses with a max of 5 or so programmers, so you can ring up and demand your $200k job?

That's not how the real world works.
