If your post is on either pages 2, 3, or 4, and you said "Stop making these threads", you are no better than the thread maker. Why re-post comments that were already covered on page 1? Why feed a child that you don't want to grow? (Ok a little cruel but you get the point) Just like the thread maker didn't have to post another Sakura thread, you didn't have to go out of your way to tell him not too, when like 10 people already did so on page 1. You didn't earn any cool points with that lol
Anyway Sakura will always be the most important female in the manga aside from Tsunade. She's forever attached to the two main characters, Naruto and Sasuke. I don't like the girl, but I don't hate her either. I'm a fan of any character development. I was happy when she got her screen time as having Tsunade-like strength and medical skills, and disappointed when she stopped getting development (I feel she got shorted a bit). Same with Hinata. I'm happy she's getting development, but I'll be upset if Kishi shorts us again. As far as usefullness, well you're only as useful as you are used. So it's a tough call there.
On another note: Are there actually more than 10 Sakura fans on NB? I swear I never really see Sakura threads, I more so see Hinata threads, and they all bash Sakura fans, but I swear its like thousands of Hinata fans and I've only seen like 4 Sakura fans ever (including 2 on this thread). Sometimes I'm like "who are you Hinata fans even talking too?" you know? lol I feel like if I did a poll thread of who was a fan of Sakura or Hinata, only 3 people would turn out for Sakura.
Anyway I'm a TenTen kind of guy myself. She's been useless since like ever. But personally I think she could beat both Sakura and Hinata, since they have that close range style to her long range style. I'll be happy once TenTen gets some shine. Then you'll probably see plenty of troll TenTen threads from me. I'll probably make a NaruTen thread just for the hell of it xd (Just kidding, I'm just serious)
