>>835 On the main page, there's just images. Think about Danbooru. On the side of the page are 9 "stickers" (Smile, frown, question mark, gentlemen's face, wtf, lol, #1, a cookie, and a heart). You can drag stickers onto images as a way to easily give feedback. Bad images get lots of frowny faces or wtfs, good images get smiley faces, #1, heart, so on. Threads work like an imageboard thread, but with one difference: You can "remix" a work. Something odd about it right now is that if you remix a reply image, rather than posting in a thread, it posts in the second image's thread.
I'll take some screenshots later and put them on the imageboard.
