SF GATE - Feb 17 - GlutenfreeSingles.com is a fairly new niche dating site that was created in July 2013. It now has ~25K users, ~6K of them are active on a weekly basis. “Niche sites are like traditional dating on steroids,” said Eli Finkel, a psychologist at Northwestern University who studies relationships. "The idea is to meet someone who is especially compatible." Niche sites help cut down some of the noise of dating online. Sam Yagan, head of Match Group, is skeptical that sites catering to smaller niches will really take off. “For one, the marketing is very hard,” he said. “How do you even reach a gluten-free single? It’s just crazy.”
