Casey:
Not really. Would Dumbledore actually want anyone to know that he 
placed the hero of the wizarding world in an abusive home?

questions?

Casey:
For all we know asking those questions may be part of Snapes first 
class every year, much like the "foolish wand waving" speach. I 
imagine he started with Harry because he was their "new celebrity". 
If Harry had answered something correctly Snape might have moved on, 
but Harry didn't. Thus he could knock Harry down from his celebrity 
status to that of a mortal. Then Harry back talked and confirmed 
Snapes worst assumptions. 

As for why Snape didn't ask about Harry's background, well, if he 
doesn't ask about the other children why should he ask about Harry?
