depends.

• according to my classmates: either ggoogle or wikipedia (i always know the answers)
• according to dos and notwin: tumblr or wikipedia...but the talk pages (i make a lot of drama on irc sometimes)
• according to my grandma: probably bing (looks like the archetype of "cute and smart good boy", aka what every grandma thinks of their grandkids)
• according to every moderator on gaming forums: 4chan (particularly /b/)

(out of context, i think wikipedia already had a gijinka)
