Potioncat:
The Sorting Hat would know that he was a half-blood, but no one else 
would. (Unless the magic quill gives the child's parents' names and 
teachers have access to it.) He doesn't know it himself. 

In the first moments of sorting, everyone would think he's a Pureblood. 
Then as people learned a little more about him, they would think he 
landed in a Muggle orphanage by some mistake. The fact that he does 
such magic give Slughorn reason to believe Riddle is from good 
wizarding stock--and Slughorn is a very tolerant Supremist.

What I wonder is, if Riddle was so good at charming people, why didn't 
he weedle an invitation to someone's house for the summer?
