narramissic writes "Google began running a live test last year that lets people rank and remove search engine results and comment on them. Testers were presented with different variations of the experiment, which the company first publicly detailed about two weeks ago in an official blog posting. For example, in one version of the test, people can only remove results, while in another they can append comments that only they can see, said Google software engineer Matt Cutts. But while implementing these features permanently would be a major step for Google in giving more participation to its users, the company remains undecided. 'It's a really fun experiment. I can't say for sure whether it will go live for everybody because we're always running a ton of experiments. Only some of those, the ones that are being very successful, are launched live for everybody,' said Cutts. In the meantime, Google is collecting data that offers some interesting search quality insights."
