Bitcoin Planet

I want to offer a central place for users to explore a network they create themselves relevant to the Bitcoin economy - this is your chance to help build a website that will help everyone tomorrow! A crowdsourced website where a user could submit a URL (checked against currently known URLS ) under one of 4 categories: "Buy Things", "Services", "News", "Trading". A clean design / rounded corners goes a long way for the display of items. Verified users (email) can comment in the style of reddit ([login to view URL]) on the relevance of the link. Comments are hidden unless selected, and users can upvote/downvote comments and links (a karma system keeps tally for the users themselves - only one upvote per user per link possible) layout and design freeform - but I want something easy on the eyes more like [login to view URL] and not [login to view URL]: 1 X welcome page displaying 4 categories + a "Best-of" category (users cannot submit to this category, it is moderated) + a reasonable "news" text section. 5 X 1 page per category. 1 X link submission page, checking against existing urls & notifying user if the link already exists. Underlying tools for storing URLs and karma system. Every page needs a 'user signin' section; as well as a "submit a link" button. Open to other tools as needed to create the site, please shoot me a msg & discuss beforehand.
