Weekly Payout?

I don't think it'll be a weekly payout. They're talking about it in the present tense "we're paying out" as opposed to "we'll be paying out". They're likely referring to updating your account balance every week. Ya, I know that they have changed it to daily, but they only mentioned that in today's blog post, so it's likely that yesterday's blog post was made with the old system of balance updates in mind. Also if you read today's blog post, they mention that they have to verify page views at the end of the month to ensure that they come from legitimate sources, which kind of rules out weekly payment.

I sort of doubt it. Maybe they meant that they work on the payroll every week? I can't imagine them paying every week, when some writers don't make more than a dollar or two each week and they have thousands of writers to deal with.
