flickr launched "Galleries"
"For whatever you find interesting, fascinating, or mind-blowing on Flickr, galleries are a way to curate up to 18 public photos or videos of your fellow members into one place around a theme, an idea or just because."

sounds nice, even though i don't understand the "18 items limitation"...
will play around with this soon.
