I have set up an appointment on my Google calender to see my physician. After visiting my physician and got back home, I received email from a random person complaining of my appointment sending them reminders. Really? So my appointments are now going to be shared with the world, that’s really not so cool, just to speak in a gentleman language. This comes to solidify this conception I have that anything you put anywhere on the internet can be accessed by someone. If its private, don’t enter it anywhere on any computer on the internet. Privacy is at the highest risk ever, so beware of what you put out there online.
