Tiles display useful information about a place, such as the place's Popular Content or Featured People. You can use a tile as is or customize it to display information specific to your place.
Streams are another type of dynamic content you can push to a place. With streams, you can add content directly to the activity stream of that place. The activity you push to a place is threaded alongside natively created activity.
Templates provide a reusable way to organize a group of tiles and activities to solve a particular problem.
