TopTenSources.com is a collaborative news project, and a rather interesting one too: when visiting the site, you face the average gossip page, only quite decluttered (some pop-ups do happen, unfortunately) and with most of the people adequately dressed for the occasion.
Once you start looking deeper, you realize that each of the news pieces are actually a mashup of internet media, like blogs, podcasts, video, and other sources; these mashups are composed by the site’s contributors (registered members, that is), so that the site takes the form of a huge collaborative blog in which unlike traditional collaborative blogs, members do not know each other, and no one overlooks the whole job. On top of the collaborators, there are the editors, who also aggregate news, only they generate RSS channels to which site visitors subscribe to, and which usually deal with more general topics, like arts, politics, travel, technology, etc. Also worthy of note is that the site is licensed under Creative Commons.
