If you need the joke explained, Moskovitz is making fun of a common tactic used by hackers: Sending fake messages which appear to come from an authority, in an effort to get people to give up their passwords. But he's got a backhanded point. If Facebook insists on using its own software to make major announcements, a fake Mark Zuckerberg has a decent chance of fooling a lot of the people, a lot of the time.

The number is higher by 10 million than the 90 million figure cited in the copy of an ad appearing in feeds for, yes, Facebook's advertising program.

Zuckerberg's profile also lets us know that his interests include "eliminating desire for all that really doesn't matter." I'm guessing he heard that at the ashram. Meanwhile, the site reminds me that sixteen of my friends have installed the Facebook application for the iPhone. So don't worry, advertisers: The site may not have it's numbers quite straight, but you can rest assured that Zuckerberg's quasi-spiritual minimalism fetish won't make him stop you from cluttering our lives with appeals to our insecurities.
