At today’s speed rate in all things (technology, fashion, politics, etc) fads aren’t uncommon at all. In fact, it seems no that fads are more long lived than other subjects at matter. The shortest fads around are the ones offered by Twitter’s hash-tags.
Anything twitters feel like talking about in under 140 characters are changing every second. For example, the highest talked about hash-tag was #lessambitiousmovies reportes by http://networkeffect.allthingsd.com/20110105/lessambitiousmovies-shows-twitter-can-still-be-community-not-just-a-tool/?mod=ATD_rss
From the simplest topics to the most scandalous ones about politics, show business, etc, are discussed even as your red this blog post. Which is why if you are indeed a twitter user, it would be very useful to have a tool just like Tweetdeck or Chromebird. These tools give you a continuous, real-time update about what’s going on with your followers and the users you follow. Who knows? You might come up with a hash-tag of your own and start the contagion.
