I'll definitely be following this website with interest; I'm a huge fan of sites that allow anonymous posting as well as how Reddit can create active communities around very niche topics (which is a lot harder on e.g. 4chan).
EDIT: I do have some problems with this rule: "Nothing that violates US law, or anything that would be considered 'gray area'." What is a 'gray area' is, itself, a gray area. I don't think the rule itself needs changing, but it would be good if it was supported by some examples of things that people might want to do but you won't allow.
EDIT2: Another issue: in a lot of fonts, Ieddit (with capital i) looks very similar to leddit (with lowercase L), which is a derogatory term for Reddit on 4chan (and possibly elsewhere) (owing to the shitty rageface memes which use the word "le")
