Twilight and Harry Potter

I have not read either books, but I have seen a few of the Harry Potter movies. I think that Twilight could gain the popularity that Harry Potter has, however it might not last as long because of the fact that there are only a few books in the Twilight series and there are 8 in the Harry Potter series. The thing that could make Twilight not gain the popularity of Harry Potter would be that Harry Potter is targeted towards boys and girls, while Twilight was written more for a female audience.
