Matt Lewis, an early adopter, explains "Why I hate Twitter":
Twitter has become like high school, where the mean kids say something hurtful to boost their self-esteem and to see if others will laugh and join in.
Of course the instant response on Facebook—or anywhere else—can be just as bad. Lewis mentions a better way to proceed:
When Abraham Lincoln was mad, he would famously write people scathing letters. He would then file them in his desk drawer, never to be sent. Abe was lucky he didn't have Twitter.
