NEW YORK — Twitter Inc.’s visitor growth cooled last month, signaling that a boost the online messaging service got from an endorsement by talk-show host Oprah Winfrey is losing steam.
The “microblogging” site drew 18.2 million users in May, up 6.7 percent from a month earlier, according to New York-based research firm Nielsen Online. Twitter logged 7.04 million users in February, almost doubled that to 13.9 million in March and then gained 23 percent to 17.1 million in April, when Winfrey signed up for the site on the air.
