I've been observing the Jump Rankings for a few months now, trying to get a handle on the rhyme or reason to the whole thing, and I think it's time for me openly accept that I have absolutely no understanding of the tastes of Weekly Shounen Jump's readership.
I mean, I look at these rankings and I see a grand total of 2 series that I think are even close to of where they deserve to be from my viewpoint (Nisekoi at 3rd and Bleach at 10th seem about right to me)
The one I understand the least is Gintama. Granted I'm a huge fan, and therefor filled to the brim with bias, but it seems to me like it's been so good so consistently for the least few months but the rankings haven't seemed to reflect that in the least.
Medaka Box's ranking is another mystery to me. I've never liked the series until very recently. In the past I couldn't imagine how it could have held on for so long but now it's finally doing things I'm actually somewhat impressed by and the ranking plunges. I just feel confused.

Apparently my tastes are just extremely abnormal when compared to jump voters.
