I first know Twitter through the ITEC’s reading.

Form the wikipedia, Twitter is a free social networking and micro-blogging service that allows its users to send and read other users' updates (otherwise known as tweets), which are text-based posts of up to 140 characters in length.

People can access to Twitter either laptop or your mobile phone anytime you want. It is the strongest point in these days because mobile phone occupies the bigger and bigger part of their life and is better to access internet than through laptop or desktop.

Twitter has interesting characters and opportunity in business.

1. Social networking site: It’s based on the relationship which is already known the person and then extends their relationship to other people who participate in Twitter. We can use the relationship based on Twitter, as like James Karl Buck case.

2. Reply culture: through the internet, all over the world, people can write the comments about the topic immediately and it can be a play to leave funny comments.

3. Citizen journalism: It’s possible to exchange their daily life without delay, so many people in Twitter can be the fastest citizen journalist in the whole world, such as China earthquake.

4. Conservation marketing: If one person writes his/her opinion about the product, anyone can add their opinions about the products on the comments freely. It can be a good source to one who thinks whether buy it or not.

However, Twitter promotes an atmosphere that people make anonymous relationship through the wireless than face-to-face. In addition, does it really need to share their every action through the internet and know other’s every movement? Sometimes, I think it needs to be far from the internet and enjoy one’s own time. I often feel many people too much be attached to appliance which can access to internet and to anonymous people.
