Of all the many forums on Webmasterworld, this is the only one I could find that will get close to my question (which all the Google guys section will also heed... .but this is not G related)
In your site presentation do you rely on CDN content? This is third party inserts, usually pics or video/audio?
If so, much of that will be blocked by a technology that is getting news in recent days: adblockers.
Have you made arrangements to avoid the blocks by producing your own content, or securing images/videos you can serve from your site?
What are your steps forward in light of this USER side tech which is growing leaps and bounds?
