There's a search bar at the top of the screen. Not only can you search for cities, you can also search for names by putting an @ in front, or search for key words or tags by placing a # in front. Our programmers are constantly expanding the search function so that you will soon be able to perform full-text searches.
On the right side of the screen, you'll also find a tag cloud. This is a collection of tags relating to popular images that are trending. If you click on a tag you find interesting, you'll be presented with the results in your stream.
