Additional: This has the potential of being abused for political reasons much like the mass reporting groups do to flag posts on Facebook and Twitter that don't align with their views, but are otherwise within the guidelines. Instead of having posts removed, however, they will just lose rank and visibility(and the owner may be none the wiser).
This would allow for those same groups to send around mailing lists of which sites to go report for political gain, hasn't there been ebough of that already?
Interesting, and dangerous, but not unprecedented. A lot of now much less fortunate countries made similar leadership decesions as we are experiencing now and it didn't end up well for them. The app smells of socialism to me, if I don't like your site because of your views I can arange for a mass campaign to make sure nobody sees it with this tool?
This isn't about rankings or quality or even search results. It's at the browser level. You'll have no way to SEO your way back into good graces, or know you've been targeted. Mob rule, indeed. And where did they come up with this "not in the top 5k" business. Are only the big brands to be served by Google in the future?
Google's adsense front page says "we value your content" as their latest app wants to flag said content for not being in the top 5k of websites? Hmm... I agree that it needs to be discussed, from a company who uses algos for almost everything this is akin to a dialup move. So why? Perhaps to have something to blame when it's later found out it was abused(and it absolutely will be).
