Internet usage: When is it time to draw the line?

Twitter, Faceboook, Myspace, etc, where will it end? Okay yes blogs are part of the internet BUT they don't share personal info, your name, identity, etc, etc. Okay, we'll start with twitter. I heard that they are going to put the word "tweet" in the dictionary, the meaning saying when you update your status on Twitter. !???! Um, okay, wow. That, that just stooped to a whole new level of stupidity. I can just hear the other countries laughing at us and our "stupid american ways" *say that in a French accent then it sounds so much better.* My definition of Twitter: An easier way for your stalkers to keep track of you. If you tweet, I'm going out of town to lets say Orlando to get to this resteraunt at this date in this park wearing this item of clothing, hmmm, how long will it take for some creepy 70 year old pedifile with thinning hair living with 46 cats and likes to watch little league games, to find you?
Or Facebook. Some people are smart and are like, okay, I'll only accept people that I know personally and have a locked profile, good for you! But then we get to the people who are like, they're hot, look around my age, no idea who he is but he only lives 470 miles away from me, what harm could there be? That old man is stalking you, beware. He knows your face and he knows where you live.
Myspace should be called, everyone's space! Same thing with facebook, it's out in the open and they can track you down! BEWARE!
That's all for now. Remember: Not everyone needs to know everything and if you see a creepy old guy staring at you intimately from across the room, run!
p.s. Remember what Mom and Dad taught you, some creeper comes up to you and you don't know him, shout Stranger Danger! (no matter if your 19 and in public,) and if someone asks if you want candy from the side of a van, tell them to throw it to you.
