Here’s how they describe what they do on their website:
We use a combination of editors and sophisticated algorithms to identify the best-regarded sources across thousands of topics. We then dynamically filter content from those sources, regardless of where it’s created (a blog, a social network, a media site, through Sulia’s publishing system, etc.), into high-quality, realtime “interest channels.” The result is streams of timely content from experts that is always on-topic, readable, and relevant.
Ease of Use
Simply link it to your Facebook or Twitter account and you are ready to start using it. It also has a handy bookmarklet, similar to Pinterest, which you pin to your bookmarks tool bar. Then simply click on it when you want to quickly post anything you find interesting directly to Sulia.
I love the interface and I really like that it aggregates sources from blogs, Facebook and Twitter. This is another example of how to stay up to date with the topics people are interested in so that you can write about it on your own blog. Are you tempted to try it?
