Who is the most popular Avenger? Apparently not Iron Man

So from Wednesday last week through till Monday, Synthesio did some correlation of social media chatter (i.e: Facebook, twitter and youtube) to calculate who the most popular Avenger (or the one that everyone was talking about) and guess what? It wasn't the generally assumed Tony Stark.

The most popular Avenger is ... STEVE ROGERS AKA CAPTAIN AMERICA

ONTD who is your favourite Avenger?
