A pseudonymous convention that let Redditors pick the name they use on the site perhaps contributes to the confessional tone of some discussions, said Mr Martin.
"There are certain things that people are uncomfortable talking about on Facebook or Twitter for professional reasons or do not want to talk about in front of friends and family," he said.
Using a fake name on Reddit gave them the chance to air feelings, attitudes and stories that they would not otherwise share, he added.
"Facebook makes me hate the people I know and Reddit makes me like the people I don't know," he said.
