I read the article where Some one was having a conversation with the founder of twitter. The author said she wouldnt open one even if she was stuck in the desert. The twitter rep said that she would wish she had one then so that she could message some one for help. That could be a benefit of twitter. All you have to do is give some one a short message on if you need help or not. I thought that was the funniest part of the interview.
The second article that I read was Fashion Tweeting. I think this could be helpful to their business becasue some times designers are far away and if they have an urgent message they can just use the site TryMyFashion to talk to any co worker. Instead of flying some where far to help some one with a fashion show all they would have to do is send them a message.
