I appreciate that Google appears to have reached out to local newspaper sites (qctimes.com, napavalleyregister.com), for Contributor. But if I were a major content publisher, the relatively small and mostly non-notable list of current Contributor sites [0] would make me think that Google isn't highly invested in this project. Which is not a good first impression considering that many people think that Google is too quick to abandon projects. They should have booked a few more major sites and media brands; right now, the 2 sites that are highlighted are the National Post and Popular Mechanics.
