在「Study finds fringe communities on Reddit and 4chan have high influence on flow of alternative news to Twitter」這邊看到的：
After analyzing millions of posts containing mainstream and alternative news shared on Twitter, Reddit and 4chan, Jeremy Blackburn, Ph.D., and collaborators found that alt-right communities within 4chan, an image-based discussion forum where users are anonymous, and Reddit, a social news aggregator where users vote up or down on posts, have a surprisingly large influence on Twitter.
依照對 reddit 與 4chan 的描述，這兩個媒體對 Twitter 的影響，會讓我聯想到在台灣 Ptt 對各新聞媒體的影響：Ptt 是很多新聞的起點？
"Based on our findings, these smaller, fringe communities on Reddit and 4chan serve as an incubation chamber for a lot of information," said Blackburn, assistant professor of computer science in the UAB College of Arts and Sciences. "The content and talking points are refined until they finally break free and make it to larger, more mainstream communities."
真的研究應該可以看出 Ptt 的影響力？
