That's the thing about open source. The original don't always work out to be better than other coin which uses its feature. Because other coin got its own feature on top of talkcoin feature. If u compare Navajo with talkcoin right now , i would say Navajo is better than talkcoin because it has what talkcoin has on top of it's own feature.

Talkcoin need new innovation feature to keep up.

New user would rather investor and use Navajo instead of talk coin simply because it got more to offer.
