why would I want to update my avatar to one of those new-fangled pokie-thingies when I already have one of the alltime greatest cartoon animals as my avatar?!
I guess if you didn't remember them from childhood, they aren't that big a deal (see how fast Lux went to 'don't care' mode). I didn't even like them much back then, but I'm a nostalgia fiend. They may not be "good anime", but I think the avi thing is more about bonding over/reveling in collective memories.
