BuzzSumo; social media search

BuzzSumo is a new social media search engine, and it's got an interesting twist to it. It focusses on the top content that's available in your area of interest. The Top Content search makes it easy for you to find the most shared content across multiple social networks: Facebook shares, LinkedIn shares, Twitter, Pinterest, G+, and totals. You can filter by type - article, infographics, guest posts, giveaways, interviews and video, and by time - 24 hours, week, month, 6 months. You can also see who has shared something, which is very helpful if you're trying to find contacts. Finally, you can also check out influencers, who are the key people in certain subject areas. It's a real nice looking tool - take a look at the interface, then take it for a spin.
