I think having block options directly on Google's search results is the right long-term answer. But this extension lets people clean up their personal results while sending block data to Google that we might be able to use as a signal to improve overall search quality.
Thanks to everyone at HN who poked us by asking for this, by the way.
Don't worry about refreshing -- I'd much rather see three good results than 7 bad ones. The idea of being able to block content farms entirely is literally making me giggle at my desk. Focus on that!
Thank you, thank you, thank you x1000 for this.
