Facebook has been feeding this revolution for months, and months. Unlike independent newspapers, Facebook was unrestrained. Clips of Mubaraks failures have been circulating FB for many, many months. Clips of families of bloggers beaten to death have been circulating through FB for many, many months too. People see what their friends have to say, comment on them, and share it. People read about how the security forces deal with demonstrations... also on FB.
There are at least 350,000 Egyptians who said they were "attending" the Jan 25 protests -a call which also started on FB.
I understand how it's "hip" to hate social network websites, but I give credit where credit is due. Egyptians have been suffering for years, police has been brutal for years, and the regime has bee failing for decades as well. The only real new player on the scene was FB.
