I really enjoy using Flickr. It can be a place to upload professional work and a place for your quick shots with a phone while on vacation. They have a decent post processing tool for your mobile pics as well. Although not advised to use when considering processing your more "professional" shots. Still it's user friendly and a great way to track your progress in your photography adventures.

Been a Flickr user for years and it's by far the best photo app out there.
