Forum:What's so good abou Vocaloid?

I want to know your guys opinion. I remembered about this poll about which singer/band would you like to perform on the opening of the 2012 Olympics, and Hatsune Miku was winning by far. It was nothing oficial, but many people were expressing their motives for wanting Miku to sing on the openings.

Anyway, I'm not posting this here asking you to vote. It's just an unofficial poll. But I wanted you guys too see the comments. What makes vocaloid so famous. Why do you guys like them so much? It's obvious that speaking about the softwares capablities, they are far from good as an human voice. Yet, Vocaloid have tons of fans.

In my opinion, they aren't humans, but they are real for sure. For me what makes vocaloid so famous, is the fact that the songs are created by many many many diferent composers and artists. Many of them doesn't have the purpose to earn money, just to share theyr talent. So, I really prefer an vocaloid song, that have an meaning, and it was made with heart, than those fake pop singers we have today.

This person said pratically everything I think about Vocaloid: http://www.the-top-tens.com/members/GoSu%60Z/blog/opinion-miku-being-first-choice-compared-others-5676.asp
