I fear that with adblocking nearing 25% market penetration we're going to see fundamental changes in the way ads are delivered in response. Maybe a transition from third party ad servers to locally hosted ads that have to be added to block lists individually. Maybe YouTube will start inserting unblockable ads directly into the video stream. Fine people like Raymond Hill will keep fighting the good fight but I wonder…
I would argue that too much of the content that is paid for is created purely to generate page-views to carry advertising.
Those people who are motivated to share knowledge and opinions sincerely are crowded out by click-bait.
