If I were looking, it would be "Current Occupation". I don't particularly care about the occupation per say, I am more concerned about whether or not they are employed, and if not, why not?
Only application I ever made was when I started with OKCupid. They told me that at my age I was too old for group sex - in spite of the fact that at the time I engaged in that quite regularly.
I guess they must have considered that the province of young people. Anyway did not matter - they put me in touch with some nice men but then I met my husband so I did not continue with them.
If I were looking .. which my husband strongly discourages ... my first question would be: "Are you married?" Seems that many people on dating sites are already married. I know they would probably lie, but I'd love to see the liars trying to look honest. :)
