They released a buggy app they didn't go about punching orphans. Their webapp is excellent and the native one will be fixed and re-released, let's get things in prospective and try to complain less about free stuff.
Siegler isn't just complaining about a buggy app - he's complaining more about the trend of Google releasing sub-par products or mis-managing their releases.
Nah, they've already released Gmail. And by the amount of stuff they release statistically they will muck up a few, luckily it's mostly easily fixable. He is just angry his "scoop" went sour.
This is the problem I think. Their web app (both for Gmail and G+) are very good, so people expect that an iOS app for the same product will also be very good.
Then they went and released the iOS app for G+ and it was woeful (and continues to be woeful after a couple of updates). I didn't get the new gmail app before they pulled it so I can only speculate (and considering they pulled it rather than left it to iterate, I'll assume the bugginess was pretty bad).
Why is it they can get a mobile web version of an app so right and get the same native app so wrong?
