Still on Web 2.0 tools - Twitter

Looks like Twitter has a gone big time in Singapore! Attended a course at TLC on 8 July to learn what's so cool about people wanting to send out tweets (140 characters). Looks like there there's no need to even create an account if I didn't want to. I could just do a search on the twitter home page if i wanted to learn about the latest buzz about stuff in town. Anyway, I did create a tweeter account for myself, well not that I have really interesting stuff to tweet about (oh well, at least not right now:.) Well, I am hoping to learn how to use this tool to complement classroom learning in the future. Here's my url on tweeter: http://twitter.com/ttwizz

Will log to an online class sometime this week to see how people use tweeter for learning via an online lesson at http://www.wiziq.com with Preetam.
