Just do a web search when logged in to your Google account, and check out all the new tools that are available. Now you can reorder results so that the site you prefer always appears first, delete a link from the search results that seems out of place, add a url so your favorite site always shows up for that search, or post a comment so you can remind yourself about a page's content or provide recommendations to other users doing the same search.

These notes will only affect your search results pages and do not impact the ranking for other users when they search on Google. But to see even more information about what other users think about a search, check out the "All notes for this SearchWiki" link, which lets you see an aggregated view of which pages have been moved up, deleted or added, as well as the comments users have added for specific sites.
