Lately I'm starting to feel that I have too many pictures uploaded on my facebook profile. Today I wanted to search one of them but I couldn't remember in which of my album it was located so it made me think of write your own TAGS for pictures (like in Flickr, Delicious, or any other...) not only to tag your facebook friends, users... Albums are useful & static but not the best way to classify & search.
C'mon Facebook!! I'm sure you can
Starting by this maybe in the near future you could create kind of lookbooks or thematics stacks with your Facebook pictures and make the most of them.
