"In less than nine months, 9GAG has more than quadrupled the number of monthly unique visitors to its site, going from 16 million to more than 70 million," said Tony Conrad, founding member and venture partner at True Ventures. "With its ability to easily and quickly spread entertaining visual content via Facebook and Twitter, the potential of 9GAG as a viral distribution platform is huge, and we look forward to working together with them to maximize this opportunity."
This seems like a large, risky bet to make on a humor site with fast growth but not much track record. I don't know a lot about 9GAG, but it seems like a case where since Funnyordie and Reddit were successful, any site with growth deserves investment.
