Hmmm, my bad then

Anywho, if Neville was the centre of the series, like someone already said, JKR wouldn't be selling as many books. Neville won't have the Dursleys, but he'll have his grandmother, who is ten times better than the Dursleys. And with his bossy Grandmother there, Neville will still be as timid and as insecure, maybe just as brave. Personally, I don't want to read about that.
I really like Harry because JKR made him to be the perfect hero, her perfect hero, and my perfect hero. See, there is NO SUCH THING as a perfect hero. They all have their faults, some more than others. But Harry is this realistic hero, with real feelings, and a personality that most people can relate to. He's felt what it was like to be unloved, unwanted... Like most of us. He's also felt what it was like to hate, real hate. He's felt a lot of things we all feel at some point [well, he hasn't really fallen in love yet, but that's why we're all here at Portkey, is it not?

] And apart from him having all these "only human" feelings and personality, Harry has the adventures. Sure, they seem a bit cliche at one point or another [we get spoofs, do we not?

] but JKR writes them so skillfully, that we don't even see it the first 5 times we read them!
I don't know about you guys, but, if the roles were switched, I wouldn't be as obsessed with "Neville Longbottom and the Philosopher's stone" or "Nevielle Longbottom and the Chamber of Secrets" or "Neville Longbottom and the Prizoner of Azkaban" or "Neville Longbottom and the Goblet of Fire" or "Neville Longbottom and the Order of the Phoenix". I don't think I'd even read it

No offense to anyone.
And there's a reason why JKR chose to write Harry and not Neville. Aside from the fact that it was Harry she saw on that train ride, Neville would take all the "fame" differently. He's been living with his Grandmother and obviously, she lives in the wizarding world. And don't go saying that she won't be here because Neville is the boy-who-lived and he's supposed to be with the Dursleys and supposed to be a near orphan because he has no other relatives and his Grandmother died. You'll be changing FAR too much, and the story will start to not make sense

Well, just my two knuts
