Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
I don’t want to place a bet that these things are going to take off — and the more I learn, the more it seems clear that “Google+” is an umbrella name for several individual services, rather than a single unified thing — but these introductory videos are really well done. Note that the UI screenshots are even set in Helvetica, not Arial. Some of the best evidence of good taste at Google I can ever recall.
Sidenote: Regarding mobile clients, Google writes:
Starting today Google+ is available on Android Market and the mobile web, and it’s coming soon to the App Store.
Not the “iOS App Store” or “iTunes App Store”. Just “App Store”.
