Maybe it didn't topple facebook, but what other data do they have from it? Is searching this information fruitful in interesting ways? It might be.

About the Google+ vs. reddit, this is the best that I could find: https://www.google.com/trends/explore#q=google%2B%2C%20reddi...

I'm not a Google+ user (at least not by choice), but as a redditor for 7 years that chart seems to show the correct trends (as far as reddit's growth is concerned, at least).
