So I finally created my Facebook profile and added some friends. What's interesting is that everyone pays attention to Facebook in near-real-time; I got friend additions within minutes of sending the requests . . . from the same people that took days to respond to LinkedIn requests and have never responded to Plaxo requests.
Here's my take-away: if Facebook is important enough to important people (think C-Level executives) that they prioritize communications from Facebook to be important enough to instantaneously respond and react to, then I totally understand why Microsoft spent so much money to invest in it and why BlackBerry released an integrated Facebook app and why everyone is developing for Facebook.
