Would a dead man have time to haunt the world by posting pictures of supermodel Gabriela Barros online? Rapper Kanye West, of course, is not dead, although “RIP Kanye West” is still the hottest-trending topic on Twitter (Pop & Hiss advises against clicking on it, unless you’re ready for a stream of baiting links to random sites).

Actually, there is something significant about trending topics – not just RIP Kanye West – because they invoke reactions. Twitter users that continue the trend are either curious or opinionated. If a user clicks on a trending topic it receives more hits or has more weight in the trend. If a user comments (or retweets) on the topic it receives more weight. Both actions keep the momentum going – the snowball effect. More importantly than the whole world talking about you (publicity) the whole world is making its own news; trivial as it may be.

The Twitter effect is included in my soon-to-be-released review of the book, Socialnomics: How social media transforms our lives and the way we do business.)
