In just a week, some 50,000 Web sites have adopted Facebook's "Like" button, along with its other new social plug-ins, the social network tells TechCrunch. Granted, 75 of those sites were Facebook's launch partners -- including CNN and The New York Times -- but the numbers and the rate of adoption is still "pretty amazing," according to the blog.
"This growth is important, because as more sites integrate these social widgets, Facebook will increasingly own social interaction across the web," TechCrunch writes. (TechCrunch says it added Facebook's new "Open Graph" features the day they launched last week.) Facebook also tells the blog that its CEO Mark Zuckerberg predicted that users would register 1 billion impressions in its first 24 hours of existence -- which actually turned out to be a conservative estimate.
