Google now allows us to reorder and annotate search results. If you log into google account, you can see 3 buttons next to each search result, including: Promote, Remove and Comment. But, any changes you made will ONLY be saved into your Google account and won’t affect others, at least for now.

Google obviously understand the beauty and power of human-editing community (e.g. Wikipedia, DMOZ), and they now encourage their massive user base to contribute to the search engine. Although Google haven’t directly linked their search algorithm with this new feature yet, they might do that in the future if they are able to collect solid and substentcial evidence to show human-editing leads to better search quality.
