From Twitter blog an interesting article about topic trends of 2009 divided by categories: news events, people, movies, tv shows, technology, sports, hash tags.
I can little talk about the sector more near to me, technology. Watching it i was sure about the hit of the new Google service, Wave, the communication and collaboration service in real time.
The same for the new operating systems by Microsoft, Windows 7; e by Apple, Snow Leopard.
And what you think will be the top trend topics of 2010?
