Today Google has retired Google Reader joining a long list of other Google products that have been discontinued. See a full list by clicking the Wordstream infographic to the right.
The reason offered by Google: “usage of Google Reader has declined, and as a company we’re pouring all of our energy into fewer products.”
I suppose it’s to be expected when you have an organizational culture where 20% of your time can be spent experimenting on new projects. Of those that make it to market as betas, many will not become viable as contributions to the business. Luckily, in the case of Google Reader there are plenty of alternatives like Feedly.
