Google killing Reader was very shortsighted because they’ve hurt the open web in an effort to promote Google+. And it was all an effort to promote Google+, nothing more.
Reader was perfect the way it was and could have been left unmaintained. Don’t tell me that Google couldn’t spare an intern for the occasional fix.
And I don’t have any numbers however I’m willing to bet that Reader was, as a social network, far more popular and active than Google+ ever was.
Also such metrics don’t count the brand damage. I will never forgive Google for killing Reader and as a result I have rejected again and again Google’s products. Even at work I just convinced everyone that we must not depend on Google’s Firebase because we can’t trust Google.
