Balatarin

Balatarin (in Persian: بالاترین, meaning the highest) is a community website through which users can post links to the webpages of their interest, with an emphasis on Iranian audience. Although only registered users can post links to Balatarin, registration was firstly free, but after a while moderator banned all new membership applications!. New links initially go to the "recently posted" page and once they collect enough positive votes, they are moved to the front page, which increases their chance of being viewed. The underlying idea is a mixture of reddit, digg, newsvine, and del.icio.us.
