Well, this is officially sad, desperate, and annoying! Google+ is now reminding us that we have no manners, and ought to thank the people who have liked (probably by accident) a link via the abandoned social network. Oh my goodness!
Now that Google is interfering with search results by jamming Plus data into our esophaguses, we have a proper way to express our gratitude. There's a convenient, distracting little link next to the distorted site in question that'll let you automatically thank your pal for playing an unwitting in the gradual suckening of Google. There's not even a question mark next to the proposition. You're commanded to thank. Thank the person. Thank them. And thank us too.
