Lots will cry if their dreams of ad-blocking on mobile go away.
Remember, ads make the web work. That's why places like Mac Rumors, Reddit, Google, Facebook, and all of your favorite sites exist. We don't want no ads, we just want the to not be right in our faces. Google is doing a lot to help with this (since they exist because of ads). They're dropping sites in their own rankings when they're placing ads in crummy places and ruining the user experience. Google only allows a max of 3 ads per page and limits them in other ways too. The sites you see that are stuffed full are generally not using the Google ad network which is the most common on the web.
