Sidewiki: Over the past few years, we’ve seen extraordinary innovation in terms of making the web collaborative. So we’ve decided to discontinue Sidewiki and focus instead on our broader social initiatives. Sidewiki authors will be given more details about this closure in the weeks ahead, and they’ll have a number of months to download their content.
Do you remember the fear and outrage about Google Sidewiki? It was all just FUD in the end… the technology was completely misunderstood by most people. Now, if the Sidewiki concept was incorporated into Google+, that could be interesting.
