Seemed Like A Good Idea At The Time

Flickr's success comes from doing what it does well, and keeping it simple whilst doing it... even the print options muddy the waters a bit. When people want video, they go to Youtube (even though others have paid for original content); when they want to store photos, they go to Flickr, which is like the world's shoebox-- some users don't even realize that their images are publicly viewable.

Personally, I find the video feature interesting, but I don't see myself using it.
