In my point of view Facebook changed our lives both professionally and presonally. It is a good thing that you can keep in touch with friends, old classmates, relatives, etc. especially with those people who are abroad. People with similar interest can share new discoveries. I am really orientated towards technology and gadgets, so I use Silverlight webphone technology for SIP calls on Facebook<snip>. I just use this for maintaining a better communication. On the other hand the information on Facebook is a treasure chest for some government agencies :). There are pros and cons.
I don't agree that Facebook has changed our lives. It's only a shift of verbal discussions to typological discussions.
I tottaly agree that FaceBook change lives, there's a lot of my friends who couldn't live without FaceBook, they just read stuipid things, upload stuipid photos and so on, in my opinion FaceBook is only good for talking with friends and for comercial.
Nowadays facebook became very famous. It facebook you may connect with very people at a time and can do communication. It is also used for business purpose. So i think every person affected by facebook.
This thread has run its course, especially because the OP hasn't come back to join the discussion.
