Twitter - by Laura

In her last English lesson Laura and I talked about a new way of communication called Twitter. Here's what she summarized:

Tweeting is posting what the user is doing, links to websites or any other information which your "followers" can read. I wonder what is the purpose of this?! Since no one has the chance to answer to the post, it is a very one-sided way of communicating. Unless the Twitterer has subscribed to you and you have subscribed to him, you don't have the chance to stay in direct contact with him or her.
So why are many people so crazy about this hype - simply because it is new? Or because of need for recognition, or to get the latest news about celebrities - because actually the Buckingham Palace and Arnold Schwarzenegger use Twitter for their announcements. Our enormous need to be up to date with the lastest news (e. g. Michael Jackson's death) is responsible for regular breakdowns of this site.
I heard of people who are addicted to Twitter. For example, the British singer Lilly Allen who has acknowledged that she spent several hours a day on this site and that her boyfriend gave her one option: Twitter or J. She decided in favour of her boyfriend.
But, in earnest, if you stay on Twitter, you can read a lot of drivel, unimportant information about people who are sitting on a bench or other stupid things. It can be true that many people, like Obama or huge companies, have the chance to profit from Twitter, but is this way of communication intelligent? Goodness knows.

Maybe someone can give us an insight here? Anyone out there using Twitter? Please enlighten us!
