I always know their name and a few basic facts (?) about them from reading their online profile. What kind of information do you value having after the first date? How does this inform your impression of the person and if you want a second date?

If they like you and what they want (booty call or serious relationship)
A little about what they like and do- so you can talk and relate interests/day life
A little about their morals/beliefs on life
Where they stand on things that matter to you
There are other things, but that's too much to expect from a first date unless you turn it into an interrogation.2
