ECONOMIST - Jan 28 - After Donald Trump was elected president, Maple Match, a dating app which connects Canadians and Americans, was inundated with people signing up. TrumpSingles.com is the opposite. It connects Trump's supporters. The site increased its monthly fee from $4.95 to $19.95 in December following Trump's victory. It enjoyed a bump in users even after the price increase. Match.com, Bumble and Tinder cater for everyone. That has left lots of room for "niche" providers. Making money is difficult, however. It is hard for new businesses to charge subscription fees while building brand awareness. "To be successful, niche dating sites need critical mass and a mobile platform," says Mark Brooks of Courtland Brooks, an online-dating consultant.
