I think part of it is that the popular ones are the ones you see around first. It takes a while to get familiar with 50+ different characters.

It's nice to think that all the Vocaloids should be equally popular and are all equal in every respect, but the fact is, the success of the popular ones is what spurred the development of most of the others. If Crypton had gone bankrupt for some reason in 2006 and never tapped the Japanese otaku market, Vocaloid might not have lasted past the VOCALOID2 era.
