I'm talking about the other responses to the OP. Lately, if Google is mentioned on HN in a story, you are pretty much guaranteed that several of the off-topic responses will be either something about PRISM, Reader, or moving to DDG/FastMail, even if the story, for example, isn't even about PRISM or politics. Reader Derangement Syndrome is another, with people seriously proposing in some comments that Gmail is a shutdown risk given Reader.
G+ is Google's centralized system for single-sign-on and account profiles. It used to be confusingly distributed over multiple services, now it is unified. Oh, and it has a news feed associated on it at plus.google.com that you can totally ignore if you want.
Some of the reactions to this are way over the top. I guess I'm burning karma points by posting this, but it is an annoying trend.
