Where's Paul Miller?

I just noticed there has been no Paul Miller action on the Verge for over three weeks (except for a verge cast).

It is of course none of my business, but I wonder how the pay schedule works for a site like the verge. Do the writers from the Verge make a living off of writing for the site, or do they get some sort of payment per article? I am unfamiliar with how online news sites work in this regard. For instance- some writers are very prolific on this site but they may only contribute one article every month or every quarter.

Assuming Paul Miller is still a full time Verge employee- I wonder what he's up to and why we don't see more output from him.
