First thoughts: Looks like digg.com, calling votes 'bites' instead of 'diggs'.  Oh, and there are 'slices' too...<p>After reading the help menu, I understand that tweeted bookmarks are the things in the list (aka 'slice'?).<p>I think the most important feedback I can give is to either include more help on the landing page (what are bites and slices?), or change the terms to be more obvious at first glance.
