Web trend alert: image bookmarking sites

Update (June 14, 2008): Victor says his project, vi.sualize.us, has been around longer than the sites I’ve mentioned here. So, again, this is another image bookmarking site worth checking out.
I smell a web trend. In the last few weeks I’ve discovered two new image bookmarking sites in addition to the insanely famous but still exclusive FFFFOUND!—We heart it and typeish.
To those who are asking “but why?”, normal bookmarking services aren’t visual in nature. Whether it’s social bookmarking like del.icio.us, or social voting like Digg, or serendipitous discovery like StumbleUpon, users decide if a website is worth visiting by looking at its name, description, tags, and popularity.
Granted, those sites are getting smarter by taking snapshots of what the sites look like, or by isolating thumbnails for if it’s an image or video being bookmarked. But it’s nice to have a dedicated tool that satiates your hunger for all things eye candy. The question is, are these image bookmarking sites effective?
