FFFFound! is a cool concept. It learns what types of images you like and creates albums of recommendations for you. Anyone can add images but, only images recommended for you are displayed in your album. They are currently in private beta so you can't register at this time but, you can still check out the site. Here's how they sum it up:FFFFOUND! is a web service that not only allows the users to post and share their favorite images found on the web, but also dynamically recommends each user's tastes and interests for an inspirational image-bookmarking experience!!
Stay tuned for them to go live.
