From the Google Blog:
We wanted to build a better group sharing experience, so we made a new app called Spaces that lets people get people together instantly to share around any topic. With Spaces, it’s simple to find and share articles, videos and images without leaving the app, since Google Search, YouTube, and Chrome come built in.
You can create a space with just one tap for any topic and invite anyone via messaging, email, a social network, or whatever way you like.
Spaces is rolling out today on Android, iOS, desktop, and mobile web for all Gmail accounts. Give it a try and create your first space today.
