But celebrities on Twitter appear to be so beyond reason.
It started off purposefully enough, with Lance Armstrong using the micro-blogging platform to tell fans about his collarbone injury and Demi Moore harnessing the power of the "tweeple" to stop one of her followers from committing suicide.
Now, the good deeds of the few are being eclipsed by the vapid musings of the many. Like John Stamos' scrutiny of sweat. And Ashton Kutcher's ode to Moore's behind. And Katy Perry's updates on the state of her inanely named cat, Kitty Purry.
What follows is not the result of a study that placed iPhones in the hands of apes in the Amazon. No, this is Hollywood at its 'tworst.'
Celebrity: John Stamos.
Act of Twitter stupidity: Sharing more than anyone wanted to know about Uncle Jesse's hygiene habits.
JohnStamos: off to sing and run on the treadmill - i sweat so much during rehearsal they call me - john stay-moist. my new porn name. yours????
Celebrity: Travis Barker.
Act of Twitter stupidity: Dredging up drama better suited for divorce court.
trvsbrkr: Your uncle is a convicted child molester @shannamoakler. Why won't u agree to keep him away from our kids? Are u really that s****y of a mom?
Celebrity: Courtney Love.

katyperry: everyone please pray for miss kitty purry, she is hearing rumors of NOT winning best pet for TC [Teen Choice] awards... & it looks like she might jump.
Celebrity: Ashton Kutcher.
Act of Twitter stupidity: Waxing poetic about his wife's behind while she's bending over before him, then posting a photo of it for all to see.
