While the news media continues its love affair with Twitter, Compete reports that the microblogging service suddenly stopped growing in May. According to the research firm's May data, Twitter registered a slight 1.47% increase in monthly visitors compared to April, totaling 19,728,619 uniques. Total visits, however, were up a healthy 6.9% to 134,536,240. Compete's numbers can't be considered completely accurate, but they are corroborated by similar findings from Quantcast, which actually showed a dip in monthly uniques for the hot Web startup.

Meanwhile, YouTube and Facebook continue their growth trajectory. Compete's data shows a minor decline in unique visitors for YouTube, but separate analysis from comScore shows that 6.8 billion videos were viewed on the Google video site in April, a 15% increase over March. In all, U.S. Internet users viewed 16.8 billion videos in April, and Google's video properties had 107.9 million video viewers. According to Compete, Facebook grew from 104 million uniques to 113 million, an 8.54% increase. Visits also grew from 1.63 billion to 1.74 billion.
