Flickr has been my app of choice for over 10 years.

I have followed its progress from a fledgling website to the wonderful sleek service it is today. Flickr never disappoints. I can back up my phone pics, share pictures with friends and family, and join in with community groups in sharing pictures of our favorite local sites. I can follow photographers I admire and get feedback from knowledgeable groups to improve my own personal performance. Flickr is a wonderful community and I am always glad to be a part of it.
