A cool feature of Usenetix is that it automatically groups similar images together into categories. You can think of a category like a mini-newsgroup, but one that exists solely for a set of like images. This makes viewing much more fun, since you don't have to hunt-and-seek through entire newsgroups to find related images.
Furthermore, you can now browse on the level of the category. That is, you only check out the categories that interest you.
