Like Digg or Reddit, InboundMarketing.com allows users to submit and vote on news stories. The difference? Stories on inboundmarketing.com are related to marketing generally and inbound marketing specifically.
How do you submit a story? It's all explained on this page: http://www.inboundmarketing.com/node/658
(Shortcut: Drag this link: Submit News into your browser bookmarks toolbar, and click on it when you have a story you want to submit.)
Let me know if you have any questions. I'm happy to answer them in this thread.
