Today, we’re announcing Google+ Collections, a new way to group posts by topic.
Every collection is a focused set of posts on a particular topic, providing an easy way for people using Google+ to organize their interests and focus areas. For Google Apps customers, collections could be used for communicating to a project team or organizing an event, allowing followers to easily access all relevant posts in one location.
Each collection can be shared publicly, privately, or with a custom set of people. Once you create your first collection, your profile will display a new tab where other people can find and follow your collections. Posts in collections you follow will appear in your Home stream, with a link to easily jump right into the collection so you can get to similar content from that author.
Collections is available on Android and the web starting today, with iOS coming later.
