Roughly, from least often to most often...and a pleasing pattern has formed. I was displeased with the previous Google Plus update, which was very like Facebook in tone and presentation, but of course I got used to it, and simplified it where I could. The new update is so simple and elegant, it's astonishing. The best thing about it is that there are options for people depending on their screen size. Also, the screen stays right where I left it and I can more easily pick up where I was last.
I think it was the right decision to move away from the Facebook-style format and toward a more Tumblr-like or even Pinterest-like one, depending on personal preferences chosen.
