It is possible that Mr Zunger woke up this morning and thought , "This is a great oppourtunity to get a bunch of vague and unsubstantiated feedback on a product that is being shutdown. I'd like to spend half my day moderating comments".
It could also be that he wanted to redirect some of the passion for google reader in a positive direction. Make Google a bit more empathetic and friendly.
It could be some combination of the two.
I don't see malice here. I think Mr. Zunger made a smart move.
Now if he actually thought he was going to learn something he didn't already know from those comments, that would sadden me.
He is smart enough to realize that comments like those have a huge power-user sample bias and are mostly useless.
My lemmings comment was way out of bounds.
