MySpace (bleh... I prefer TagWorld) does at least offer a little more personality to the old school pen pal business. I have quite a few asian friends who are very outgoing and talkative, but its a joint effort between the two connected people.
The blogs that TW has help a lot, because you can open yourself up to whatever is on your mind and those who subscribe to them can see your sincerity.
But I can see how asian girls can get offended. Otaku guys seem to live too much in their anime fantasies in their regards to girls from japan...its really quite sad they get treated as objects sometimes rather than a person with feelings.
