You may not have it yet, but the first group of Facebook users are now being prompted to activate their very own Facebook-powered e-mail accounts.

When I logged on this morning, I got one of those out-of-the-blue updates letting me know that "messages" had changed. Facebook chats, messages and e-mails would now be centrally located in one place as conversations (Google Mail-style). Wait . . . e-mail? Had Facebook finally partnered with Google for a total takeover of my online experience?

Not yet. But the social networking site has launched its own e-mail service; users' addresses are simply their username@facebook.com.

I didn't activate mine. (Unlike some other Fbook features, that is — so far — optional.) It's problematic to me for a number of reasons: First, I don't necessarily trust Facebook not to disseminate that info and give random spammers still-more access. Two, whether it distributes that address or not, it's pretty easy to guess/build a robot to spam you. Unless a user sets their profile to be totally unsearchable, all you'd have to do is track down their username and pop an @facebook.com on the end to hound them incessantly. Three, don't I already have an e-mail address? Why do I need another, more public one?

Tell us: Will you be activating Facebook e-mail? Do you buy the hype that Facebook replacing phone numbers is next? Tell us in comments.
