Ask HN: Any startups focused on social news trends?
I'd like to know of a few examples of startups that tackle trending news topics based on number of stories, user engagement, social media stats etc
Found a few good examples in NewsWhip: http://www.newswhip.com/news-app/europe and http://timeline.com and wonder if there are any other approaches. Now that I think about it, mashable.com is a great example.
