1) Google+ makes it easy to unintentionally plagarize. Case in point, he wasn't able to easily get from a re-share to the original.
2) Google (the search engine) should NOT rank a Google+ post which is itself a clone of an actual article above the article itself. (Quote: 'But my query for "jon mitchell jury duty" didn't mean "Show me what my Friends+ are saying about 'jon mitchell jury duty.'" It meant "Show me Jon Mitchell's article about jury duty!"'.)
3) The Google+ web app is ugly.
4) Google (the company) is forcing you use your Google+ profile to identify yourself.
Summary) Google+ is a bad service.
You can disagree or agree with the above points, but simply quoting individual sentences doesn't lead to positive discussion.
