Google SearchWiki

Google's experiment that lets you reorder and annotate search results
is now live. Google SearchWiki should be available automatically if you
are logged in to a Google account and it can be recognized by the
visual clutter added to the search results.

Next to each result,
you should see three new options: a way to promote a web page at the
top of the results, an option to remove results from the page (they're
still visible at the bottom of the page) and a feature that lets you
share public comments about a result. After promoting a result, Google
shows some unnecessary information about the other people who promoted
the result.
