Endless personalized (/-able) photo&image stream. I want my screen full of an endless stream of images, which I can customize both by "liking" or narrow by keywords, such as "now I want to see artsy black&white photos" or "show me men's fashion". I expect the images shown both in general and in specific cases to cater to my taste.
