Besides too much personal information and being a conduit for “borrowing” access to your home computer, it can also provide links to your office computer.
I work for a national company and it advises us to use LinkedIn and Facebook.
I have multiple business websites, because customers expect it.
I am an officer of a non-profit organization, and we put our contact information there, too.
I have had genealogy information on the web for over ten years.
I own a house with numbers on the curb. All that is public, including who I make payments to.
I am fascinated about why people are worried about privacy, when there is so little to begin with.
Sure some bad guys might try to harm me, but they often get caught pretty quick. Somebody recently charged a few tanks of gas on our credit card number. The plastic cards never left our possession, bills were not paid online. We don’t know how it took place.
The oil company cleared it up quickly and completely. If they had not, we would not have paid, and would have cut up the cards; which were 1960s technology and business practice, I must add.
