For many people that won't be a problem - I think of those who already use Facebook inbox regulary, many of them already more often than e-mail. I've found out myself doing it more often recently. Why? It's easier and more convenient - when I write a message to John Doe I know exactly to who I am writing, with e-mail you have to remember which e-mail was whose, or which of the e-mails of Joe Doe that you have is that correct, latest one; and the same with phone numbers and SMSes. Yes, in a big scale of things, moving your communication with others to Facebook isn't the best idea ever, but in a day to day hurry you often forget about the great, big things and just stick to what's seems easier and faster now. That's why I think this has all the chances to actually be successful, for better or worse.
