/jp/ - Otaku Culture

I haven't seen it anywhere at all outside of 4chan, but I'm fine with that.
The characters are not "current" at all anyway, the only reason you'd give a shit about them is if you liked tech enough to nostalgia over old operative systems. I don't believe OS-tan ever had any big memes surrounding it either aside from a dance gif or two.
Even the newer ones (Nanami, Yu, Ai, Touko) aren't really popular. People are more content to make new -tans of consoles (all over again) and browsers than they are OSes because the average normalfag doesn't know anything about OSes or the inner workings of a computer.
