1x.com is a photography sharing site; however it is a non-standard one. Unlike Flickr it is an edited site meaning that every image entered is evaluated for aptitude in the 1x vision. As such it is a neat place to browse, but not really a place for people without an artistic bent to submit.
Another thing that sets it apart is the critique section.
A fun part of this site is the random image "Stumble" option. A Fukung-esque makeup just click the image for a new one.
One hit against it is that in order to save on VisulizeUs the image must be opened in a new tab, you cannot do it directly from the site.
So I've found another site. Vi.sulize.us. It's a lot like We Heart It, except it allows me to take images from near anywhere (including if I open a tab of just an image) and by just right-clicking rather than opening a restrictive frame. So weee~
