Improve Google search results: Personal Blocklist
Google has finally realized that their search results have suffered lately. Trying to find genuine information has become more difficult with the advent of aggregator sites, associated content and “news” media. In response to this, Google has released a plug-in to Chrome: Personal Blocklist. Install it, and Google search results will be accompanied by a link for blocking domains.
A useful extension, but keep in mind that you agree to let Google freely use this information “to improve our products and services”.
