Open Graph is a development tool that lets third-party apps and sites report your activities back to Facebook. It’s meant to extend or replace the Like button. It’s a way for sites and services to jack directly into Facebook from anywhere. If companies use Open Graph, they can publish to your Ticker and Timeline, too, effectively sending tattle-tale updates on anything you do to everyone you know, in real time. And then Facebook gets to keep that data forever. It is the ultimate collection tool, a way for Facebook to monitor you, wherever you go.
A friend of mine noted recently that I seemed a little antagonistic about Facebook recently — mostly on my Facebook account, which is some irony for you — and wanted to know what I had against it. The answer is simple enough: Facebook is what happens to the Web when you hit it with the stupid stick. It’s a dumbed-down version of the functionality the Web already had, just not all in one place at one time.
If you you aren’t already paranoid enough to remove your address and cell phone number from Facebook, today might be the day. Facebook has decided to give its third-party app developers API access to users’ address and phone numbers as they collectively get more involved in the mobile space, but privacy experts are already warning that such a move could put Facebook users at risk.
