But not necessarily because of social. From co-founder Eli Pariser in All Things D:
What’s interesting is that so far the major social referrers have been a smaller part of Upworthy than might have been thought. Facebook is starting to be important — Upworthy is now up past 425,000 Facebook fans, with about half of them joining in the past month — but “We haven’t been really good at Twitter as a traffic source,” said Pariser. So far, Upworthy has found that Twitter is ”a great place to interact with a community, but people on Twitter mostly want to talk on Twitter,” he explained.
Upworthy just raised $4 million from venture capital firm NEA and a collection of Angel Investors.
