Scoop.it is also a content discovery platform very similar to a more visual Twitter.
1. Create a topic that your users will be interested in.
2. Add a "Scoop.it" bookmark onto your bookmarks bar.
3. Go to your website, and click on the Scoop.it bookmark that you had saved.
4. Bam, your content is now ready to be discovered.
Note: This is a channel that takes time to build up traffic. However, it does give you decent traffic eventually if you keep your participation up.
