So why...

Yeah she's some hot girl who plays word games and other educational themed stuff. My guess is that it's a test to see if men would be willing to learn more as long as a pretty girl is doing the teachin. Or something like that. Honestly I can't see why else she's on YouTube.
 
I think she's hot. Hot and smart - the perfect combo, as far as I'm concerned. Do you think her eyes are really that blue?
