Simple to use, good website design and intuitive. never had any problems with it.

The interface is so clear, which makes it easier to advertise, in my case, my brother's artistic photographs.

It is easy to store and share photos on Flickr. It is easy to find friends. Flickr can be used to share photos for Creative Commons Licensing. The amount of space on Flickr for the free account is 1 TB which is also a pro of Flickr. Flickr allows for great organization of your photos, too, which can come in handy. It is nice to be able to see what others have posted and shared which really adds to Flickr. You can also make a book from your photos with a partner company that it embedded into the site. There are a lot of options with Flickr including upgrading to a Pro Account which is what some are looking for.
