[citation][nom]zoemayne[/nom]come on you gotta trust google more than facebook. google has the best software engineers.. and remember the quote from mark where he couldnt believe how people were so stupid and just gace all their information to his website.. i cant find it!![/citation]
You gotta remember, though, he was 19 when he said that. Facebook was Harvard-only, and he had no clue what it would later become.
What would you say if you were 19, and you made a little, dorky website that you thought would probably go nowhere, and all of a sudden, people are submitting personal information and details by the thousands. I'm pretty sure my reaction would have been the same: "lol, these people are stupid."
In fact, that's still my reaction to people posting shit to facebook without realizing the potential impact it could have.
I have facebook "friends" that I don't really know that well (e.g. acquaintances from college classes, people I met once or twice at a party, etc.). I generally don't want these people to know my phone number, ergo, I don't post my phone number to facebook. I won't even mention the home address field.
People see a place to put their phone number or their home address on their facebook profile and they fill it out. They don't stop to think whether they should; it's there, so they provide it willingly. Then they complain when some creeper shows up at their house in the middle of the night, and they blame facebook.
Facebook and/or Google+ can implement all the privacy features/controls/safeguards they want. It won't prevent stupid people from doing stupid things.
To quote a wise man, "You can't fix stupid."
