>Last year we completely re-wrote the Google+ Web app from scratch. Rather than rebuild every nook and cranny that developed over the five year history of Google+, we started with a clean slate of the features people used the most (based on our data & research). We then released this preview version to collect feedback and find out what people missed the most of what we left out.

Proof that Google+ 1.0 was an enormous flop.
