Looking for educators from Southeast Asian countries to share some experiences using Web 2.0

If you're from Southeast Asia countries (Malaysia, Indonesia, Thailand, etc) or have taught students from the Southeast Asia countries, would you please share me your teaching experiences using Web 2.0 tools in your classroom? Is there any particular tool(s) that you used, what work well and what didn't? Did you or your students have difficulty in accessing the tools? What is the biggest concern in integrating Web 2.0 in your classroom? I would like to hear some experiences, especially if you're teaching in an online course. Face to face experiences are welcomes too.

Thanks,

Aira
