Design is nice, but the UI/information architecture is confusing - lot of information that I don't understand, and the nomenclature is awkward. I would suggest showing less information, i.e. you don't need to show who submitted the links on every "slice," considering that all the slices on a page are inherently connected to one person. I think you could get rid of the "see original tweet" text as well, and maybe just show the bird somewhere if you really need that feature (although I think it can be removed).
