The numbers tend to disagree with you. Unless you think that only hacker news users are on git... Given VIM is bundled with OSes, i would never expect neovim to take it place in usage numbers (unless OSes start adopting neovim as well)... but when it comes to actual interest, in just about every measurable aspect, neovim is coming out on top of developers who actually know about it.
Most devs I work with use it (if they use vim at all), I've seen it more than VIM lately at conferences as well. You give up nothing using it an gain a bit (and will gain much more as its further developed)
