CHICAGO TRIBUNE - Oct 27 - The League, an invite-only dating app, has just launched in Chicago. Of the 2k accepted Chicago members, 9% have an MBA, 5% have a law degree, and 3% have an M.D., the company said. 13k daters are on the waiting list, according to the company. But when they pride themselves on accepting only the cream of the crop, niche apps might have to sacrifice growth for reputation. Mark Brooks, an online dating industry analyst who runs Online Personals Watch, cited services like BeautifulPeople.com and other dating sites that proclaim themselves to be "elite." To grow, "Do you start being not so elite?" Brooks said. "These apps are limited in how much they can grow."
