27 people who chose None of the above said they use Name.com which puts them at about 1.7% of the total.

I probably should add them to the registrar list -- thanks for bringing it up.

Ditto. Been using them for the past couple years (only have a few domains with other registrars). They have good prices, no ads or upsells (well, almost none), they don't spam me, and they focus exclusively on making setup and management of DNS easy.

Most other services try to provide about 300 extra services (from hosting to hosted apps and junk I don't care about), and not only spread their support too thin, but make the entire experience (initial purchase to setup to maintenance) less efficient.
