I leave the salary field blank because I was told that "$250,000-$500,000" seemed obnoxious, and that I should instead signal my income with the words "comfortably successful" in my profile, with a full reveal later. I'm not sure that that's good advice; what do others think?
Of course, my profile might be obnoxious anyway. You tell me: http://www.okcupid.com/profile/TalkingHead68
Revised.
