I went to look but it was a couple of days ago, and that's hundreds of messages down the list in my Mentions tab on Twitter. And with 140 chars, I'm basically scanning for grunts and snorts. But I can do you better. Here's a list of all my links for the last few months. Some of those go to GP articles. Those are the ones people are complaining about.

Looks like all you have to do is search for plus.google.com in that list. :-)
