So what accounted for the tremendous growth in March and April? In March, Twitter started
to attract significant media attention after Compete.com reported that the number of
Twitter users had skyrocketed in February.
In April, Twitter's profile was enhanced when Ashton Krutcher (aka @aplusk) waged a
public race against CNN to be the first to have one million followers. Then, on April 17, talk
show celebrity Oprah Winfrey (aka @oprah) started using Twitter, making her first Tweet on
her show with help from Twitter co-founder Ev Williams.
Although April did show impressive growth, it was also the first time in nine months that
Twitter had a decline in month-over-month growth.
