inappropriate.

why do people post such inappropriate things of facebook, twitter, myspace, etc?  recently i have noticed a LOT of inappropriate posts, my bestie katie and i were just talking about how strangely inappropriate people have gotten with their postings. perfect example would be the king and queen of inappropriate ashton and demi.  apparently they were 'sexting' on twitter a week or so ago, gross. her poor children.  also, why are people constantly posting unflattering information about themselves on these sites?  here are some recent examples: 'had to move up north to get clean...' why are you oversharing? 'i have custody now since srs took my kids from their mother' seriously?!?!  also one last... 'are you pregnant with the same baby daddy?'
i mean i know i share my 'funny but klutzy' stories online, but never anything like the above.  what is the world coming to?  you can view more inappropriate posts for example this gem: http://www.lolfbmoments.com/?p=844  it is actually pretty hysterical, but seriously what is this world coming to?
