Every collection is a focused set of posts on a particular topic, providing an easy way for you to organize all the things you’re into. 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 give you a great way to find more of the stuff you love from the people you follow.
