Join WHAT?

Believe me, I am into modern technology.I have a couple computers (and have since '83), we both have cell phones, plus digital this and that. We both e-mail and use the cell phones, plus our land line, but ... Twitter, and FaceBook, and MySpace, and WHAT? HEADTIME? I don't get it. How much time do we all need to talk to friends and relatives?
I do not condemn anyone for posting their life in front of the whole world, but do not ask me to.
A couple years ago, while doing some work at a high school, I asked a kid who was between classes and talking on her cell phone, "WHO ARE YOU TALKING TO?" She replied, "MY FRIEND OVER THERE", as she pointed to another girl across the school yard. I am sorry, but that is pure lazy. Teachers have trouble with kids passing answers to tests by texting to each other. Classes are interrupted by ringing phones and people cause auto wrecks due to eating and texting while driving.
Now to my original point. More people are losing their identities because thieves steal it from sites like FaceBook, Twitter and MySpace. More people are stalked, scammed and been taken advantage of. In some cases, it has lead to an injury or fatal ending. If you don't believe me, read the June 2009 issue of AARP Bulletin with the story titled "FALSE FRIENDS".
This all may sound very grim and nothing but negativity, but it's meant as a caution. It is probably because one of the above happened to someone I know, and it was not pretty.
One last word...if you use these communication sites, always use extreme caution and be aware you have exposed yourself to everyone who is on the internet, not just your friends and family members. Be careful out there, and e-mail me when you get off the phone.
