Google+: Communities and photos @ Official Google Blog.

Today Google+ is the fastest-growing network thingy ever. More than 500 million people have upgraded, 235 million are active across Google (+1’ing apps in Google Play, hanging out in Gmail, connecting with friends in Search…), and 135 million are active in just the stream.

This enthusiasm, we think, stems from our building tools that build real relationships—in a live hangout, around a breathtaking photo, or with an inner circle of friends. So today we’re launching two new improvements that help bring the nuance and richness of real-life sharing to software.

Google+ Communities: for all the people you ought to know – From photography to astronomy (and everything in between), Google+ has always been a place to crowd around common interests and meet new people. What’s been missing, however, are more permanent homes for all the stuff you love: the wonderful, the weird, and yes, even the things that are waaay out there. With Google+ Communities there’s now a gathering place for your passions.

It’s beta! Here’s Adafruit’s community – Makers, Hackers, Artists and Engineers!
