Remember when Twitter was just a little pipsqueek, with less than 10 million monthly unique visitors to its site worldwide? That was back in February, 2009. Fast-forward to April, and Twitter’s U.S. visitors alone reached 17 million. Now comScore has released its worldwide numbers and it estimates Twitter’s global unique visitors in April, 2009 was a whopping 32 million, up from 19 million in March, 2009.
