given what she's wearing after the 2 year jump, I don't think that's it...waaaaaayyyy too much netting.

In the manga, the only purpose Ino has ever served is as a foil to Sakura and another female. Which is cool and fine...I mean, Tenten has pretty much only served to showcase Temari and admire Neji and again, be a female ninja. And actually, Tenten strikes me as being MORE interesting than Ino...maybe it's because she's connected to Shikamaru-who's popular-and Sakura-a central character, that makes people focus on her?
