Google announced the end of seven services this week.  Here are the services and their end dates.  On their blog, they readily admit that the products did not have the impact they had hoped.

Google Bookmarks Lists: “an experimental feature for sharing bookmarks and collaborating with friends.”  End date: December 19, 2011.

Google Friend Connect:  Allows webmasters to add social features to their sites with a few “snippets of code.”  The service is being deleted for all non-Blogger sites on March 1, 2012.

Google Gears:  On December 1, 2011, Gears-based Gmail and Calendar offline will stop working across all browsers, and later in the month Gears will no longer be available for download.  Google says,” This is part of our effort to help incorporate offline capabilities into HTML5, and we’ve made a lot of progress. For example, you can access Gmail, Calendar and Docs offline in Chrome.

Google Search Timeline is a graph of historical results for a particular query.  The information will still be available through google.com/trends or google.com/insights/search

Google Wave: Development on Wave stopped over a year ago, but as of January 31, 2012, it will become read-only and on April 30, it will shut off completely.  They recommend Apache Wave and Walkaround to achieve the same results.

Knol:  Knol was created to “enable experts to collaborate on in-depth articles.”  Sounds like Wikipedia a little bit.  They are now working with Solvitor and Crowd Favorite to create Annotum.   End date: April 30, 2012.

Renewable Energy Cheaper than Coal (RE<C):  Yes, Google was doing research to drive down the cost of renewable energy.  They have published their results and admit that others are “better positioned” to continue the research.
