Propeller is a social news portal, meaning that it is programmed by you – the audience. Our members post links to stories from all over the Web. Many of these stories originate from the websites of traditional media, including newspapers and magazines. But you will also find many stories that seldom pop up in the mainstream. Perhaps it does take a village – or at least a large community of news-hungry citizens – to nudge certain stories into the limelight.
The appearance of a story on Propeller is only the beginning. Once the link has been posted, you can vote on it, comment on it, share it with friends, or bookmark it to read later. In this context, news is not simply a pile of facts to be absorbed. It is a conversation. It is a process. And above all, it is fun: not a word we always associate with the news.
Propeller is not an absolute free-for-all. It is a moderated site, meaning that we oversee the posts, conversations, and other activity. In part this is to weed out the spam and objectionable content that are the bane of the contemporary Web. But we also maintain certain standards of civility. Members who lob personal insults or racial smears will be ejected. So will sock puppets and stalkers of any kind. This oversight is performed by our editorial staff, with the help of the Propeller Scouts. But we also rely on the community, which alerts us to abuse and in that sense polices itself.
