Google SidewikiHaving used Google Sidewiki in the past I received an email from Google announcing that the service will close on 5th December.  That’s a bit of a shame in my book as I found the service gave users the oportunity to contribute helpful information alongside any page that they found useful and thereby make the page more relevant to both them and others.

I shan’t exactly mourn its loss, but clearly there just weren’t enough users on Sidewiki to justify its existence.  Elsewhere other Google products have suffered a similar fate, such as Google Code Search, Google Labs and Google Buzz, among others. Clearly Google is trimming down its non-core and failing experiments.
