Savvy content publishers are celebrating the announcement of what may be a potentially lucrative revenue stream.

Oprah's well publicized first tweet on Friday was definitely a boon for Twitter. According to Hitwise, 37% of all visits to Twitter last Friday were from new visitors, and Twitter's overall share of U.S. Internet visits increased 24% on Friday. It is important to note, though, that Twitter, being the new and growing service that it is, usually gets about 32% new visitors every day, which definitely puts these numbers into perspective. Hitwise, however, also notes that Facebook's ratio of new visitors was only 8% in March.

While Twitter's sudden mainstream appeal might be somewhat disconcerting for early adopters who would prefer it if Twitter wasn't suddenly the cool new thing to try out for soccer moms, it will surely bring a lot of new opportunities (and challenges) for Twitter.

While Ashton Kutcher and CNN are trying to be the first to hit 1 million followers on Twitter, Joseph Frieschel, an inconspicuous Australian MD, is quickly catching up. Frieschel only opened his Twitter account last night, but he already has over 200,000 followers. How can this be? Well, it looks like the anonymous members of the infamous 4chan imageboard didn't like the idea of either Kutcher or CNN breaking the 1 million follower barrier before they got a chance to make their presence felt.
