I took this to mean that before you met in real life, you researched the other person so intently you felt like you'd spent 2-3 evenings together (talking) already? Is that what you meant?

I dunno, in my experience OKCupid profiles (the best available online dating site the last time I was single) were just a thin veneer of bullshit designed to sell only the best qualities. Nothing wrong with that per se but I never felt like I learned anything real about a person other than a few facts sprinkled in here and there.
