Google Spaces is a miniature social network for group sharing
Google's latest smartphone app, Spaces, is miniature social network designed for group sharing. Available for iOS, Android, and on the web, Spaces is essentially a messaging app with tightknit Chrome, YouTube, and Google Search integration. On mobile, spaces users can share content from any of these sources without leaving the app. Each shared item attracts its own comment thread.
Users are able to create multiple Spaces, each with a different set of participants. Participants do however require a Google account.
