Sure - it is an accelerating effect. The higher the rate of ad-block readers, the less reviews will be written which will in turn result in less readers. Can't come as a surprise really. I will not spend more time on writing reviews just to keep the revenue stream constant (which would be unrealistic anyway - the ad blocker rate is accelerating way too fast). Sorry to say but I will not work for 1-2$ an hour - and taking images of charts and the following analysis is just that - work. If people don't appreciate anymore what we are doing ... well, such is life then.
PZ is purely ad-driven. We have the donation button up there but the monthly "income" from that is something between 0-100$. As for the costs the math is easy - cameras, computers and studio gear that has to be replaced every once in a while, server costs, software subscription costs and, of course, rental costs of lenses and covering the losses due to buying/selling lenses - I also have an extra office room just for PZ (which I wouldn't need/rent without PZ, of course). That accumulates to costs of $30.000 per year or so.
Sure, a part of running PZ is fun but at some stage things are no longer sustainable.
Anyway, don't worry for 2016/2017.
