do you think celebrities tweets are original?

I agree with you that I doubht that the celebrities may ask their assistants to help them to post tweets. As usually the celebrities are very busy and they may not have time to post tweets. And they even have no more time to read the replies. I love China

In my own opinion, some are not. Since they are celebrities, they need to expound their resources to be known by other people.

I am a fan of twitter and have been using it from many years. approx 3 years running...As far as i know the celebs on twitter are for real and only they tweet it. Try to observe from where they are tweeting also. Half of them tweet through their Blackberries and Iphones which i don't think they give it to their assistant or workers. To be precise they are for real and many of them have been verified by tweeter executives itself. As far as publicity is concern they have many other tools to spread it other than tweets also. Regarding quotes and other philosophical tweets they must have copied it from somewhere or must have got from some message like we normal people do.

There are many celebrities who hire someone to write tweets for them because of their hectic schedule. You'll never know it that celebrity is really the one tweeting. But for me, I have this one celebrity that I was following, and I know that it was him who really is tweeting. I always watch his videos and interviews, and I know it's him because of his sense of humor. His attitudes on his tweets are the same. And he doesn't tweet much, only if he's free. :)
