Otakon is in town for the weekend. Staff rolled out the setup yesterday and today the hordes arrive. Here's the rub, otaku aren't the geekiest out there, but as a whole they're pretty grody.
Look, I'm just going to say it: There are a lot of geeks out there for whom the flak with regards to personal hygiene and social skills is not undeserved. In addition there is a particular brand of geek-girl who, by simply being very likely the only (but possibly one of very few) girl(s) that will speak to/associate with geek boys has essentially attained queen-b status. 90% of otaku fall into those two categories (oddly enough, yaoi fangirls not so much).
So, that's thing the first. Thing the second would be convention behavior for certain geek groups. Which, look, there's just something that happens when a lot of geeks come together and it's rarely pretty. Sure, I want to go to Comic-Con (I also want to go to E3), but it pretty much stops there. Those are conventions where the pull (in my book) is worth the horror show that is geeks en mass. I'm not saying they're all huge neck-beards. Most of them are quite average looking (cos-play aside).
At any rate expect photos over the weekend.
