SF CHRONICLE - Nov 26 - eHarmony seems a little archaic. For Grant Langston, eHarmony's new CEO, the challenge is making the site relevant to the hook-up generation. "We don't have any interest in a person who just wants to pick up someone," said Langston. "But there are people using Tinder who are not looking for a hookup," he said. "We've learned that people in their 20s and 30s who have income are very happy to spend more in the search for a more enduring relationship," Langston said. "When you're in the 40s and 50s that changes. You can see the impact of relationships that don't work out. You see bitterness. To reach people in that limited window, eHarmony must make itself easier to use," Langston said. In early December, eHarmony will release features that will make communications feel less like email and more like IM. eHarmony also wants to explore video. The biggest problem, though, is price. Tinder is free and eHarmony is $57 a month. There's also the problem of people associating eHarmony with older people.
