Without wanting to politicise, it seems my addressing Twitter was rather timely! Twitter is playing a large role in the political happenings of Iran at the moment. Information is being passed on and rallies organized. It’s no wonder that this internet tool is blocked in some countries as its power of mobilization is even stronger than that of facebook. The reason being that in Twitter you are accessible to everyone, not just your friends.
If you have joined Twitter, I have a task for you.
On the right hand bar of your home site you will find a search box, and under that there is a list of the trend topics. Just click in any key words related to the news, teaching, or any other topic that interests you and see what happens.
