Do anda think Harry shud have got together with Ginny this tahun instead of Cho?

Well, even though I don't really like Cho.... I think that how J.K Rowling introduced the Harry/Ginny couple was perfect for me :) So no, I like how they get together in HBP. OOTP might be too early for this ;)

harry really didnt see how independent ginny became until HP6... she started using hermiones saran this tahun and harry realized how attracted he was 2 her after she had proven 2 him that she was not the shy girl he had known 4 so many years

No. It was lebih realistic to give the characters at least one other cinta interest before setting up the final pairings.
