miku still gets 1,000-1,500 a month, as I said before and I'm repeating it, her closet rival is Gumi with a average of 500 a month. After her is Rin with 300.

Most of the vast majority of Vocaloids don't have anything above 50 uploads a month.

Take note, this information is based on results not largely impacted by her V3 release. Miku has mostly remained unchanged in terms of overall popularity since 2009, even with V3 vocals being released before she got hers. the Vocaloids people look up have changed, but the vocaloids people are buying and using have not. :-/
