That would be nice,but many of us don't live near each other.For example,some of us live by the Pacific and some by the Atlantic.Our parents would most likely not let us travel that far to go to an anime convention(at least,my parents won't xD)..But it's nice to dream..=w=
It's a cool idea but most of us live far too away from each other to meet up somewhere. For example some of us live in New York, Texas , California, etc..etc. I don't think that our parents will let us travel alone that far away just for a con. (For me to travel alone to met someone I met online , like hell that will ever happen. )
It's not good since we all live in different places. You really think parents will buy tickets to go another country or city for one con and with people we only know here.
I live in Europe but I bet most of you live in the states.
