Editorial Recently, a story about people mistaking a news story for the Facebook login page has received considerable media attention. It's currently being seen by many as justification for the recent trend in locking people out of their computers for their own protection - but anyone with even basic mathematical skills and a calculator should come to the conclusion that this story has been blown way out of proportion.

As of writing, there are 1631 comments on the ReadWriteWeb story, and Facebook has "more than" 400 million users. [...] about 0.04% of Facebook users.

@Thom: I never graduated college, but I'm pretty sure that your percentages are off by a factor of 100.

1631/400million = 0,000004 = 0,0004%
163100/400million = 0,04%

You indeed need to go back to college, as the formula for calculating percentages goes like this:

(a/b)×100=x

Where a is the number you want to know the percentage of, b is the total, and x is the percentage. In other words:

(1631/4000000)×100=0.04%.

Holy crap, I totally suck! I'm a friggin' moron. The original poster was totally right, my numbers are way off because for some weird reason I'm making the calculation with 4 million instead of 400 million!

Heh, this is what we call the backflip FAIL. Fixin' the numbers right away. D'OH!
