It would be great to meet people... but seeing as it's an international site and none of us are made of money: it isn't going to happen.
But hey, if anyone wants to fly their butts to Japan: I'm willing to hang out with them.
Quite a few of us from the old AO ~have~ met. Though it took years and our own initiative to accomplish.
I've met Sedka, Tych, and Keiichi when they came to Japan... I keep just missing Ewdi in Osaka... I've met up with Trunks and Jin in the US... I've had phone conversations with C.C. and Caz... lunch with some random kids here and there who's handles I don't remember.
Other AO-ites went on a trip to Otakon together once...
It's more an issue of HAVING friends already and then deciding you want to go visit them or finding out people are nearby and meeting up.
The likelihood of everyone meeting up at a single event in a single place is... well... non-existant. And since it would likely be in the US: everyone in Asia, Australia, Europe, Africa, Canada South America, Central America and the Middle East would be left out of the loop anyway.
